Four user-visible lag sources tracked down from a wider audit:
- Tab click was running three full querySelectorAll walks per click
(remove active from all tabs, all views, find new tab). Replaced
with delegated listener on the tab bar plus cached node maps;
tab switching is now O(1) and a no-op when clicking the active tab.
- saveSettings awaited saveHosterSettings + saveGlobalSettings
serially and then re-fetched the full config from main. With
autosave firing on every keystroke this added 100–200ms of IPC
stall per input change. The two saves now run in parallel and the
post-save getConfig refetch is gone — we know the new state.
- showContextMenu rebuilt hosterCounts (queueJobs.forEach) on every
right-click. Replaced with a length-keyed cache; right-click on a
5000-job queue no longer pauses while counting.
- Recent-panel shift-click was querying every .recent-file-row in
the DOM and re-parsing data-order. Reuses _recentSortCache.result
instead, O(visible) vs O(N).
