Bring the Tracks tab up to the Favorites precedent.
- Group-by (Off/Album/Artist/Name) with visible album/artist header rows + an
A-Z jump strip for Name (over the loaded set); show-album hidden under album
grouping. Group mode persists via a new locallibrary_prefs.rs (favorites_prefs
precedent; default "off"), loaded in navigate_local_library before the tab
derives.
- Multi-select toggle (toolbar) + per-row checkbox (TrackRow multi-select-mode)
+ MultiSelectBar with the Tauri Tracks subset: Select all / Add to queue /
Play next / Add to playlist / Clear (no make-offline, no remove).
- derive_tracks (reduced port: local folder_alpha_key, no genre filter) +
TRACKS_CURRENT selection-source cache (cloned in apply/append before the move)
so bulk resolves ids -> LocalTrack in DISPLAY order with no DB round-trip.
- playback::enqueue_local_tracks (source-aware via local_queue_track; reversed
for play-next); per-row play-next/queue wired in on_track_action.
- Add-to-playlist for local + qobuz_download via PlaylistPickerState.local-mode
+ on_pick i64 branch -> db.add_local_track_to_playlist; Plex rows skipped
(decided on the underlying LocalTrack.source, not the remapped TrackItem one).
- No-match empty state added.
