Three Phase-11 wins.
1. Streamlink stream quality is now configurable. config.streamlink_quality
defaults to "best" (preserves prior behaviour) but can be set to source,
1080p60, 720p60, 720p, 480p, or audio_only via a new dropdown in
Settings -> Download. The chosen quality is passed as STREAMS to
streamlink with ",best" appended as a fallback so an old VOD lacking
the chosen rendition still completes. Used by both the queue
downloadVODPart and the standalone download-clip IPC. The whitelist is
enforced via normalizeStreamlinkQuality so an arbitrary string in the
config file falls back to "best".
2. Per-item completion notifications. Default off because long queues
would spam the OS notifications panel. When enabled (Settings ->
Queue zwischen App-Starts checkbox area), every successful download
pops a "{title}" notification whose click brings the window forward
AND opens shell.showItemInFolder on the produced file (or the
download folder if the file is gone). The end-of-queue summary
notification still fires regardless.
3. Download-path writability check on selectFolder. The renderer now
asks the new check-folder-writable IPC after the user picks a
folder; if isDownloadPathWritable returns false, a warning toast
surfaces immediately instead of the next download failing with a
cryptic "datei zu klein" / "ENOENT" error. Save proceeds anyway —
the user might be picking a USB-stick path that is offline at the
moment.
Plus DE + EN locale strings for every label/option/hint, all wired
through applyLanguageToStaticUI for live language switch.

Three Phase-10 wins.
1. Streamer-list filter + bulk-remove. Above 6 streamers (the magic
number where the list starts to feel cluttered) a search input
appears below the section title and a small bulk-remove "x"
button next to it. Filter is title-substring, case-insensitive.
Bulk-remove honours the active filter — when the input is empty
it confirms removing the entire list, when filled it confirms
removing only the matching subset. Used a confirm() dialog with
the matching count interpolated into the locale string.
2. Cutter drag-and-drop. Dragging a video file from Explorer onto
the cutter tab now loads it directly — no separate Browse click.
Uses Electron's File.path extension on the dropped File object
(works through contextIsolation:true). selectCutterVideo was
refactored into loadCutterFromPath + a thin wrapper so the drop
handler reuses the same loading logic. dragenter/dragleave count
adds visual outline on #cutterPreview while a Files drag is over
the tab. Falls back gracefully if the dropped file lacks .path.
3. Per-streamer VOD scroll position. Switching streamers used to
reset scroll-to-top, painful when cycling between archives.
vodScrollPositions Record<streamer, scrollY> persisted to
localStorage, capped to 32 entries to bound storage. Save fires
on a 250ms scroll-debounce timer + on every selectStreamer
transition. Restore happens 80ms after renderVODs paints (lets
the first chunk settle) so scrollTop has somewhere to land.
Plus: bounded the persistence table at 32 entries, locale strings
DE/EN, all wired through applyLanguageToStaticUI for live language
switch.

Four wins from a deep-audit pass.
1. Windows taskbar progress bar. While downloads run, mainWindow.
setProgressBar(0..1) shows aggregate progress on the taskbar icon
(visible while minimised). New activeDownloadProgress map tracks
per-item fractions because main's downloadQueue.progress field
is not updated mid-download (only renderer streams progress).
Cleared via clearDownloadProgress in processOneQueueItem.finally
so the bar resets when the queue idles.
2. VOD card data-* refactor. The previous inline-onclick template
strings did escapedTitle = title.replace(/'/, "\\'").replace(/"/,
""") and then interpolated that into onclick="addToQueue('...')".
Edge cases (titles with backslash, ', etc.) could break the
JS parser. All identity now lives on data-vod-id / -url / -title /
-date / -streamer / -duration on .vod-card. A delegated click
listener on #vodGrid reads the dataset at click time and
dispatches to openClipDialog / addToQueue / openExternal. Plus:
clicking the thumbnail / title / meta now opens the VOD on Twitch
in the OS default browser.
3. Right-click context menu on VOD cards. Items: "Open on Twitch",
"Copy VOD URL" (uses navigator.clipboard, toast confirmation),
"Trim VOD", "+ Queue", and toggle "Mark as downloaded" /
"Unmark downloaded". The mark toggle hits a new
ipcMain.handle("mark-vod-downloaded", id, mark) so a user can
add or remove entries in config.downloaded_vod_ids manually
without re-downloading. Menu auto-closes on outside-click /
Escape / scroll. Repositioned to stay inside the viewport.
4. userIdLoginCache now bounded (insertion-order eviction at 4096).
Was Map<string, string> with no cap; setUserIdLogin helper
centralises insertion + eviction. Long-running sessions with
thousands of unique streamer lookups no longer accumulate the
reverse-lookup table forever.

Three companion features around the 4.5.22 already-downloaded badge.
1. "Hide downloaded" toggle in the VOD filter row. Persisted to
localStorage so power users who keep it on across sessions don't
re-flip it on every launch. Filter applies before the title-search
filter so the match counter stays consistent.
2. "Reset downloaded list" button in a new Backup & Maintenance
settings card. Confirm-dialog before clearing, IPC returns the
removed count for a "cleared N entries" toast. Renderer refreshes
its config copy + re-renders the VOD grid so badges disappear
immediately. No files are touched.
3. Config export / import via dialog.show*Dialog. Export strips
client_secret (should never travel as plain text via cloud sync),
tags the file with __exportVersion + __exportedAt. Import runs
the JSON through normalizeConfigTemplates so out-of-range fields
fall back to defaults; if the imported file lacks client_secret,
the existing value is preserved. After import the renderer reloads
config + relocalizes if language changed + re-renders streamers /
settings form / VOD grid.
DE + EN locale strings for every label, button, toast, and confirm
dialog. New backupCardTitle / backupCardIntro section header in
Settings.

Two real UX wins.
1. Auto-resume queue on startup. New checkbox in Settings -> Download
("Queue beim Start automatisch fortsetzen"). When enabled and the
persisted queue has pending items, processQueue() fires ~5 seconds
after did-finish-load — long enough for the user to see the queue
and pause if they did not actually want this. Default off so the
existing behaviour (explicit Start click) is preserved on upgrade.
The Settings auto-save fingerprint includes the new flag and
syncSettingsFormFromConfig restores it. Tooltip explains the
timing on hover.
2. Already-downloaded indicator on VOD cards. Config gains
downloaded_vod_ids: string[] (bounded to 4096 latest entries).
Every successful queue-item download appends its parsed VOD ID
(or every component ID for merge groups). On the VOD grid each
card whose vod.id is in the set gets a small green checkmark
badge in the top-right plus a slightly dimmed thumbnail, with a
localized "Already downloaded" / "Bereits heruntergeladen"
tooltip. The lookup builds a Set once per render so it stays
O(1) per card. The renderer refreshes its local config copy on
every "newly completed" queue update so the badge appears live
without waiting for a settings save.

Three Phase-6 wins.
1. Cutter & Merge tab labels were the same i18n gap as the trim-VOD
dialog before 4.5.20: Dauer / Aufloesung / FPS / Auswahl / Start: /
Ende: / Schneiden / Zusammenfuegen were hardcoded German in
index.html. Each got an id + setText wiring + DE/EN locale strings
(cutter.infoDuration / .infoResolution / .infoFps / .infoSelection
/ .startLabel / .endLabel; cutter.cut + merge.merge already existed
for dynamic state, now also used as initial text on btnCut /
btnMerge).
2. Per-item retry button on failed queue entries. The existing
"retry failed" queue-action retried ALL failed items at once;
when only one specific item should be retried (e.g. transient
network blip on one URL), the user had to remove every other
failed item first. New ipcMain.handle("retry-queue-item", id)
resets that single item to status: pending and triggers
processQueue if idle. A small ↻ icon now sits next to the
remove (x) button on items in the error state.
3. Status bar queue summary. The footer previously showed only the
connection status + version. With longer queues the user had to
scroll the queue panel to see how many downloads were active
versus pending. New span between the status indicator and the
version reads "{downloading} dl, {pending} queued" (locale-aware,
hidden when queue is empty). Updated on onQueueUpdated and
onDownloadProgress so it stays live.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three small UX wins.
1. Trim-VOD dialog: every inner label was hardcoded German in
index.html (Start:, Ende:, Startzeit (HH:MM:SS):, Dauer:, Start
Part-Nummer..., Leer lassen = Teil 1, Dateinamen-Format:, Zur
Queue hinzufuegen). EN-mode users had a German dialog. Each
element now has an id + setText wiring + DE/EN locale strings.
2. Settings -> Twitch API card now opens with a help line + link
to dev.twitch.tv/console/apps. Uses window.api.openExternal so
the link opens in the user's default browser instead of the
Electron renderer (which has nodeIntegration off / no native
navigation). Fixes the "no idea how to set this up" first-run
friction.
3. Settings -> Live Debug Log gets an "Open log file" button next
to Refresh. Uses a new ipcMain handle (open-debug-log-file ->
shell.showItemInFolder on DEBUG_LOG_FILE) so users no longer
have to navigate manually to ProgramData. As a small defensive
bundle:
- get-debug-log: lines parameter capped at [1, 5000] so a
misbehaving renderer (or future feature) cannot ask main to
slice millions of lines.
- export-runtime-metrics: now uses writeFileAtomicSync (the
fsync+rename helper from cycle 1) instead of plain
writeFileSync so a power loss mid-export cannot leave a
half-written metrics file at the user-chosen path.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two related Phase-4 changes.
1. main.ts: tBackend(key, params) helper with DE/EN tables for every
user-visible error / status string produced server-side. Previously
every backend message was hardcoded German, so EN-mode users saw
German errors in the queue (last_error), in download progress
status, in clip-download responses, and in the preflight panel.
~30 keys covered: invalidVodUrl, streamlinkMissing, fileTooSmall,
integrity*, downloadCancelled / downloadPaused, attemptFailed,
retryingIn, statusBytesDownloaded, mergeGroupFileMissing,
notAllPartsDownloaded / notAllClipPartsDownloaded, ffmpegMerge/
SplitFailed, diskSpaceShortFor, all preflight* messages, etc.
classifyDownloadError extended to recognize EN equivalents
(streamlink not found, no video stream, folder) so the retry
classification still works correctly when the language is EN.
The hand-rolled translation table in renderer.ts:downloadClip is
gone — backend strings are already locale-correct.
2. styles.css: --border-soft CSS var added to :root and the
theme-light override. Inline styles in index.html for the VOD
filter input / sort select / bulk bar were referencing
--bg-secondary / --text-primary / --border-color (which don't
exist) and falling through to dark hex fallbacks (#222 / #fff /
#444), producing a dark patch in light theme. Now uses
var(--bg-card) / var(--text) / var(--border-soft) which both
themes define.

Two complete UX features.
1. Streamer list is now drag-and-drop reorderable. The order is
persisted via the existing config.streamers save path, so it
survives a restart. The dragstart-then-click race that would
normally fire selectStreamer when the drag is released is
suppressed via a 50ms post-dragend window.
2. VOD cards each get a top-left checkbox. Selecting >=1 card opens
a sticky action bar above the grid with "+ Queue" and "Clear"
buttons. Bulk-add iterates the selected URLs and calls addToQueue
for each, with a single per-batch toast summarizing the outcome.
Selection is cleared on streamer switch (per-streamer mental
model) but not persisted across reloads (stale selection across
restarts is more confusing than helpful).
Implementation notes:
- Click-on-checkbox is handled by a single delegated listener on
vodGrid (initVodGridSelectionDelegation), not per-card inline
handlers. The card .selected class is toggled in place to avoid
re-rendering the entire grid on every check.
- Streamer items are rebuilt from createElement so the existing
`event.stopPropagation(); removeStreamer(...)` inline pattern
is replaced with a real listener; defends against unusual
characters in streamer names even though Cycle 4 added the
4-25-char alphanumeric regex.
- styles.css: position: relative on .vod-card for the absolute-
positioned checkbox; .selected ring highlight; .dragging
opacity for streamer drag.
- DE / EN locale strings for the bulk-bar; setText / updateBar
hook into applyLanguageToStaticUI so the bar count updates on
language switch.

After a download completes there was no way to jump to the result
without manually navigating the download folder.
Server-side:
- DownloadResult and QueueItem gain optional outputFiles: string[]
(single entry for VOD/clip, multi for parts/merge-group splits).
Threaded through every downloadVOD / processDownloadMergeGroup
branch into processOneQueueItem which attaches it to the queue
item on success. Persisted via sanitizeQueueItem so the actions
survive a queue file reload.
- New IPC handlers open-file (shell.openPath) and show-in-folder
(shell.showItemInFolder), both with existence + type checks.
- The "downloads finished" Notification gets a click handler that
brings the window to the foreground and opens the download folder.
Renderer-side:
- Expanded queue-item details now render an action row when
status === completed and outputFiles is non-empty.
- "Open file" only shown when there is exactly one file (so multi-
part downloads do not surprise the user by opening just part 1).
"Show in folder" always shown.
- DE / EN locale strings + a graceful toast if the file was moved
or deleted between completion and click.

Three small UX wins.
1. Auto-update: "Skip this version" button on the update modal.
Stores the dismissed version in localStorage; subsequent automatic
update-available events for the same version are silenced (banner
hidden, modal not opened). Manual "Check for updates" overrides the
skip so the user can change their mind. The flag is cleared once
the version is actually downloaded so a stale entry never masks a
future update. Skip button is hidden in the "ready to install"
state where it would not make sense.
2. addStreamer now validates against Twitch username rules
(4-25 chars, [a-zA-Z0-9_]). Previously bad input fell through to
the API and the user saw a silent "streamer not found" message
instead of being told the input was invalid.
3. Smart Queue Scheduler checkbox got a hover tooltip that explains
what enabling it actually does ("prefers shorter VODs and older
queue entries first"). Users were disabling it without knowing
what they were turning off.
DE + EN locale strings added for all three.

Match the dialog title exactly. Fits on the button width and removes
the last "Trim" / "Trim VOD" inconsistency.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Follow-up to 4.5.13. The dialog title was renamed but the VOD-card
button that opens it still read "Clip", which kept the same
overloaded-with-Twitch-Clips ambiguity it was meant to fix.
- DE: "Zuschneiden", EN: "Trim" (kept short for the small card button;
the dialog itself still reads "Trim VOD" / "VOD zuschneiden")
- buildVodCardHtml now uses UI_TEXT.vods.trimButton instead of a
hardcoded "Clip"
- changeLanguage now also calls renderVodGridFromCurrentState +
refreshVodSortSelectLabels so the button label and sort-select
options update live on language switch (the existing addQueue label
was suffering the same staleness)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The dialog cuts a custom time-range out of a VOD; calling its result a
"clip" was overloaded with the separate Twitch Clips feature (which
this project handles in the dedicated Clips tab). Renaming the modal
title disambiguates without touching the per-VOD-card "Clip" button
(still the right verb for the action that opens it).
- EN: "Trim VOD"
- DE: "VOD zuschneiden"
- index.html static fallback updated to match the DE locale

The Trim-Clip filename-format radio group only offered three presets
(simple, timestamp, custom template). Users who organise their archive
with the global filename_template_parts pattern (e.g.
08.05.2026_Part07.mp4) had to switch to "custom template" and retype
{date}_Part{part_padded}.mp4 every time.
New "parts" preset:
- index.html: 4th radio option, span#formatParts for the live preview
- types.ts + renderer-globals.d.ts: filenameFormat union extended
- main.ts: makeClipFilename branch produces ${dateStr}_Part${padded}.mp4;
sanitizeCustomClip whitelists "parts" so persisted queue items with
the new format survive a restart
- renderer.ts: getSelectedFilenameFormat returns "parts"; live preview
via partNum.padStart(2, "0")
- DE/EN locales: clips.formatParts label
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds a sort selector next to the existing filter input. Five modes:
newest first (default), oldest first, most viewed, longest first,
shortest first. Concrete user pain — long archives previously had no
way to find the longest stream, the most-watched, or to scroll back
to the start chronologically.
- vodSortKey state persisted to localStorage as
twitch-vod-manager:vod-sort and validated against an enum on load,
so an unknown stored value falls back to date_desc
- renderVodGridFromCurrentState now applies sortVods before
filterVodsByQuery so the filter sees the sort and the match counter
is consistent
- sortVods uses created_at timestamps for date sorts, view_count for
views, and a tiny vodDurationToSeconds parser (XhYmZs) for duration
- DE + EN labels for both the "Sort:" prefix and the five option
texts; refreshVodSortSelectLabels re-runs on language switch
- syncVodSortSelect on init preselects the persisted value before
any VOD load so the dropdown reflects state immediately
Browser-default keyboard nav (arrows, type-ahead) covers keyboard
access for the select.

Two server-side changes touching different paths.
1. fetchPublicTwitchGql now retries on transient HTTP (408/429/5xx) and
network-layer failures (no response). Up to 3 attempts with
exponential backoff + jitter (400ms * 2^(n-1)). The previous
catch (e) { return null; } swallowed network blips on the public
fallback path, which is what every user without a client_id hits
on each VOD list load — a single TCP RST produced an empty list
and the user had to click refresh. GraphQL errors[] are still
returned without retry (application-level query rejections).
Recovery is logged via appendDebugLog so we can later see whether
the retries actually pay off in production.
2. shutdownCleanup() consolidates window-all-closed and before-quit.
The two handlers ran nearly identical cleanup blocks but had
drifted: only window-all-closed killed children and was
platform-aware. The helper kills activeDownloads + activeClipProcesses
+ currentEditorProcess with try/catch, persists config + queue,
then stops timers (debug-log flush moved AFTER persistence so any
save error reaches the log before the timer is gone). An idempotent
shutdownCleanupDone flag makes a follow-on event a no-op.

Filter row above the VOD grid lets the user search the loaded archive
by title. Concrete user pain: streamers commonly have hundreds of VODs
and the current UI only supported scrolling.
- vodFilterInput / vodFilterClearBtn / vodFilterCount in index.html
- localized placeholder + clear-button title (DE + EN)
- vodFilterQuery state persisted to localStorage as
twitch-vod-manager:vod-filter so the search bar survives reloads
- renderVODs split: it now caches lastLoadedVods + lastLoadedStreamer
and delegates to renderVodGridFromCurrentState which applies
filterVodsByQuery on every input event (no re-fetch)
- empty-state DOM is now built with createElement + textContent (via
setVodGridEmptyState) instead of an innerHTML template, even for
locale-only strings — defence in depth
- keyboard: Ctrl/Cmd+F focuses the filter when the VODs tab is active
(Electron has no native find bar, so the default is suppressed). Esc
clears the filter when the input has focus and content. Esc still
closes modals first if any are open.

Two server-side fixes for separate clip/queue/editor crosstalk paths.
1. download-clip IPC was unsafe in three ways:
- reported success: true on exit code 0 even with empty files
(Twitch sometimes returns a manifest with no segments)
- passed clipInfo.broadcaster_name straight to path.join, so unicode
/ spaces / punctuation in display names produced odd directory
layouts on Windows
- the spawned streamlink process was tracked nowhere, so window
close orphaned it
Now: sanitize broadcaster_name + title, ensureUniqueFilename so
re-downloads do not overwrite, post-download size + integrity check
(16 KiB floor + ffprobe via validateDownloadedFileIntegrity), proc
tracked in activeClipProcesses and killed on window-all-closed.
2. currentProcess (a single ChildProcess global) was shared between
cutter/merger/splitter and downloadVODPart. The real bug: while a
queue download was running and the user kicked off a video cut,
pressing the queue's "Stop" button iterated activeDownloads (fine)
AND called currentProcess.kill() — which by then pointed at the
cutter ffmpeg, killing an unrelated cut.
Renamed to currentEditorProcess, confined to the editor pipeline.
downloadVODPart no longer touches it. The fallback kill calls in
remove-from-queue / pause-download / cancel-download are gone — the
activeDownloads loop above each was already authoritative.
window-all-closed now also kills activeClipProcesses.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- loadConfig now checks isPlainObject(parsed) before spreading over
defaults. Non-object JSON (array, primitive, null) is logged and the
app falls back to defaults instead of silently polluting the config
with array indices or dropping values.
- loadQueue runs every entry through sanitizeQueueItem which validates
the status enum, clamps progress to [0, 100], validates customClip
and mergeGroup shapes (with sanitizeCustomClip / sanitizeMergeGroup
helpers), and demotes stale status="downloading" entries to "pending"
with progress=0 on cold start. The previous filter only checked
typeof id/url/status === "string" and let through whatever shape
customClip / mergeGroup happened to have.
- The stale-downloading normalisation fixes a real user trap: after a
hard kill mid-download, the queue persisted status="downloading", but
no download was running on next launch and start-download only resumed
paused items, leaving "downloading" entries stuck.
- Bonus: CustomClip and MergeGroupItem imports now have call sites
(previously unused-import warnings).
docs/IMPROVEMENT_LOG.md gains a Cycle 2 dated section.

Renderer-side polish bundle.
- updateQueueItemProgress now looks up items by [data-id] selector instead
of array index. Resilient against queue/DOM divergence between renders.
Determinate vs indeterminate progress logic tightened.
- Active tab persisted to localStorage on every showTab; restored on init
via loadPersistedActiveTab (whitelisted to known tab IDs so a future
rename cannot strand the user on a missing tab). Page title now only
shows the streamer name on the VODs tab — it no longer leaks into
Settings / Cutter / Merge.
- Escape closes the topmost open modal regardless of focus (clip dialog,
template guide, update modal — in that priority order).
- Ctrl+1..5 (Cmd+1..5 on macOS) jumps directly to a tab. The existing Del
(delete selected) and S (start/pause) shortcuts still work and remain
blocked while typing in inputs.
Adds docs/IMPROVEMENT_LOG.md (new, single dated section for this cycle).

Two server-side correctness fixes for parallel downloads and crash recovery.
1. Atomic file writes survive power loss / crash mid-write.
saveConfig and writeQueueToDisk used writeFileSync + renameSync. Node's
writeFileSync does NOT fsync — a power loss between write and rename can
leave the renamed file empty or truncated, and the next launch silently
falls back to defaults / empty queue.
New writeFileAtomicSync helper: openSync + writeSync + fsyncSync +
closeSync + renameSync (with the existing Windows copy fallback). fsync
failure is non-fatal (some FS reject it) but file ordering is preserved.
2. Per-item claimed filenames fix the parallel-download race.
With max 2 parallel downloads, processOneQueueItem.finally was calling
claimedFilenames.clear() — wiping every parallel item's claims when any
one finished. In the window between an active item claiming a filename
and streamlink actually writing the first bytes, a third item could
compute the same filename and both downloads would race the same path.
New Map<itemId, Set<filename>> tracks claims per active download.
ensureUniqueFilename(path, itemId) registers per-item;
releaseClaimedFilenamesForItem(itemId) removes only that item's claims.
splitMergedFile gained an itemId parameter for the same reason. The
dead releaseClaimedFilename(path) function was removed.
Build: tsc clean. Tests: smoke + smoke-template-guide + smoke-full + merge-split
+ update-version-logic all pass. No new ESLint warnings.

The old formula (avgSpeed * expectedDurationSeconds) simplified to just
(videoDuration - elapsedTime), showing 59min ETA for a 60min part after
1min of downloading. Now uses streamlink's actual progress percentage:
ETA = (elapsed / percent) * (100 - percent), which reflects real download
speed rather than video length.
