Add an expandable search (title / artist), a sort QbzSelect (Default / Title A-Z / Title Z-A / Artist A-Z) and a Shuffle header action (play a random visible album) to the Albums tab. albums-visible derives from the full albums set via derive_albums (shared model on the no-filter/default fast path, filtered+sorted clone otherwise — the label.rs::derive_releases pattern), and the count reflects the filter. cc
