Add a custom download virtualizer with fixed 40px package rows, 38px file rows, overscan, and pinned rename rows.
Keep the downloads model logically complete so header selection, shift ranges, and actionable selections operate on every filtered expanded row instead of the rendered DOM window.
Render the virtualized body inside the existing downloads table scrollport without adding a second scroll context, while preserving column drag data attributes, row click behavior, context menus, and disabled native package dragging.
Cover bounded rendering, full logical row selection, scroll window geometry, pinned inline rename rendering, and responsive scrollport CSS with focused tests.
Complete zero-width sidebar collapse with synchronized bidirectional motion, add package-row selection and guarded double-click disclosure, render continuous selection edges across nested package boundaries, expand regression coverage, and update the public English changelog and package metadata for v2.0.20.
Rebuild downloads, link collection, settings, history, and statistics around a responsive desktop shell with compact account and queue tables, contextual navigation, persistent update affordances, unified overlays, and accessible keyboard interactions.
Add safe history-folder reveal IPC, responsive 2560/1920/1366/1120 coverage, deterministic visual fixtures, focused component regressions, and release-tree exclusions for internal working files. Bump the public application version to 2.0.13.
