Handle explicit MPRIS Play/Pause without toggling paused playback, remove the 10,000-favorite cutoff, and sort albums by original release dates. Isolate Library filters by tab, include purchased release dates, and support server-ranked artist popularity with safe pagination. Validated with 766 Qt tests, QML checks, release-sort regressions, and a release build. Refs #750, #751. cx

// Vertical A-Z jump strip (favorites/FavoritesView.slint:398 `AlphaStrip`;
|
|
// LocalLibraryView.slint:577 is a 1:1 lift of the same component). 18px
|
|
// gutter, 15px rows, 9px semibold muted letters that go accent on hover.
|
|
// Emits jump(ordinal, index); the host scrolls its own view — exactly like
|
|
// the Slint, which scrolls proportionally on the grouped grids (:1996) and by
|
|
// row index on the uniform track list (:1687).
|
|
//
|
|
// PROMOTED from views/local/AlphaStrip.qml, unchanged except for the import
|
|
// depth — same move QbzMultiSelectBar made and for the same reason: the Slint
|
|
// component was always shared (Local Library albums/artists/tracks AND the
|
|
// Library favorites tabs), so the "local" folder was a naming accident. The
|
|
// old views/local/AlphaStrip.qml is GONE; this file is the only copy.
|
|
// Call sites: views/local/{LocalAlbumsTab,LocalArtistsTab,LocalTracksTab}.qml,
|
|
// views/library/{LibraryAlbumsList}.qml and views/LibraryView.qml.
