The scan progress tile offers Pause and Resume. A paused scan releases its foreground service and wake lock, shows a paused notice, and resumes from the next unscanned file.
Repo cards, category chips and the Store search field scroll over the plain page background, where a backdrop blur changes nothing visible but re-filters each panel on every scroll frame. MornyeGlass.navigation gains samplesBackdrop; these panels keep the same tint, rim, shadow and glass clarity without the blur pass. Floating chrome keeps its blur.
Fresh staging tables hold no path keys, so the first row for an id no longer issues a delete. Removing scanned paths now runs in one transaction with a subselect instead of committing a lookup and two deletes per chunk.
Android froze the process once the activity stopped, because only track downloads held a foreground service. A dataSync BackgroundWorkService with a partial wake lock now covers library scans and in-app APK downloads, and stops when the last task ends or the system timeout fires. Its notification shows the existing localized progress, so no duplicate appears. If Android refuses the service, work continues as before.
On iOS a scan holds its own background task; on expiry it cancels the scan cleanly instead of being suspended.
Long-pressing a song in Library search results enters multi-select with the Library track actions. Taps toggle songs, select all covers the visible songs, back leaves selection mode, and a new query clears it. Applies to the Mornye Library tab and the Material/Songs search.
The Library list's multi-select toolbar (FLAC upgrade, re-enrich, convert, ReplayGain add/remove, delete) becomes LibraryTrackSelectionBar, and its delete flow becomes deleteLibraryTracks. The Library list renders and behaves as before; other screens can now offer the same actions.
Artist Tag Mode gains "Primary artist only": downloads and re-enrichment write only the first credited artist to Artist and Album Artist, so players list one artist. The FFmpeg MP3, M4A and Vorbis embeds and the AC-4 path now honor the mode; MP3 and M4A previously ignored it.
Manual metadata edits, lyrics embedding and format conversion keep existing or typed credits joined instead of dropping names. The picker scrolls so three options fit on small and landscape screens. Closes#618.
