Add a source-wide "Select all" across all playlist groups, and make one click queue every indexed video (the previous 100-per-click cap is gone). Bulk download skips items that are already downloaded or in flight, so it can't enqueue duplicates, and it includes failed/canceled ones so it also retries them. Make the UI hold up at channel scale (1000s of videos): virtualize both the Downloads queue and the Library item list with @tanstack/react-virtual so only on-screen rows hit the DOM, memoize the queue row so they don't all reconcile on every progress tick, and batch the enqueue so queuing a whole channel stays O(n) instead of O(n^2). - VirtualList: reusable windowed list that owns its own scroll container - DownloadsView: virtualized, flex-filled queue - LibraryView: groups flattened to rows; virtualized panel above 100 rows, inline below so small sources are unchanged - QueueItem: React.memo - downloads store: addMany (one state update + one pump); sources: enqueue the whole selection via addMany, no cap Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
