Playlist management: - Add/remove tracks from playlists via right-click context menu - Create new playlists (right-click Playlists sidebar header) - Delete playlists with confirmation dialog (right-click playlist item) - Playlist view removes track immediately on delete (optimistic) - Deleting currently-open playlist clears the track view Gapless playback: - Single long-running audio thread owns AudioOutput; CPAL stream stays open between tracks eliminating device teardown/startup gap - Decode runs inline on the audio thread; command channel polled via try_recv() so Pause/Resume/Seek/Stop/Play all work without spawning - New Play command arriving mid-decode is handled immediately, reusing the same audio output for zero-gap transition - Position timer reduced from 500 ms to 50 ms for faster track-end detection - URL/metadata prefetch: when gapless is enabled Qt pre-fetches the next track while the current one is still playing ReplayGain: - Toggled in Settings → Playback - replaygain_track_gain (dB) from track audio_info converted to linear gain factor and applied per-sample alongside volume Qobuz dark theme: - Background #191919, base #141414, accent #FFB232 (yellow-orange) - Selection highlight, slider fill, scrollbar hover all use #FFB232 - Links use Qobuz blue #46B3EE - Hi-res H badges updated to #FFB232 (from #FFD700) - Now-playing row uses #FFB232 (was Spotify green) - QSS stylesheet for scrollbars, menus, inputs, buttons, groups Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
