The track list shared out its whole clientWidth across the resizable columns while every row spends 24px on the favourite column and 2x8px on its own padding before the first one starts, so the grid was always exactly 40px wider than the box holding it and the last column was clipped at every size (scrollWidth 1280 vs clientWidth 1240, measured). Both numbers now live in one place and are read by the two call sites that had written them out separately, which is how they came to disagree. The enforced minimum was 512x384, which the layout had never supported: at 700x480 the eleven sidebar items needed 406px of a 352px pane, overflow:hidden cut the last two off with nothing to scroll, and Settings and Jobs could not be reached at all. The pane scrolls now, the sidebar collapses to icons below 900px (its .collapsed mode existed and only a manual drag ever reached it), the subtitle hides at the same breakpoint so the title stops wrapping out of the 4em bar, and the minimum is 800x600 - measured as where the shell still works rather than picked as a round number.
YellowJacket
Music how it was meant to bee.
YellowJacket is a fast, cross-platform desktop music player for your local collection. It plays your files, keeps your library tidy, and helps you discover and organize your music — all in a clean, responsive interface. No accounts, no streaming, no telemetry: just your music on your machine.
Runs on Linux, macOS, and Windows.
Features
Play your music
- Plays MP3, FLAC, OGG Vorbis, and WAV
- Play, pause, seek, and volume control with a mute toggle
- Gapless, glitch-free seeking backed by a read-ahead buffer

- Shuffle and repeat (off / all / one)
- Picks up right where you left off — remembers your track, position, and volume between sessions

Keep your library organized
- Point it at your music folders and it scans them automatically
- Reads tags and embedded cover art, and de-duplicates artwork so it isn't stored twice
- Incremental sync — only new or changed files get reprocessed, and deleted files are cleaned up
- Browse by album, artist, or genre, or search across everything
- Mark favorites and see what you've been listening to with play history
- Edit track tags directly when something's off
Playlists
- Create playlists, drag tracks in, and reorder them
- Smart playlists that build themselves from rules (by genre, rating, play count, and more)
- Pin a default playlist and spot duplicate tracks at a glance
Discover and clean up (powered by MusicBrainz)
- Explore — browse artists, releases, and genres from the MusicBrainz catalog, not just what's already in your library
- Auto-tag — match your files against MusicBrainz to fill in correct artist, album, and track metadata, with a review step before anything is written
- Lyrics search — find a track by a line you remember
