- A ▾ cut from the right end of the Library button (shown once there's a
friend) opens a popup of friends. Choosing one enters friend mode: the
button becomes "<Name>'s Library" in light purple, the sidebar lists
their shared playlists with a UFO follow toggle on each, and the content
area is their library — browse only, nothing plays or edits.
- A cassette column on the far left and cassette buttons on every artist
and album: pressed grey = send me this, medium grey on hover to let go.
An artist cassettes all its albums and tracks (a snapshot).
- Bottom bar: Hide tracks I have (exact matches: artist, album, title,
length within 2 s); close matches show light grey. Size of what's
cassetted against free space: orange when Syncthing would stall at its
free-space floor, red when it won't fit.
- Save and Close writes requests.json; Cancel discards; the ▾ or quitting
with changes asks Save / Don't Save / Cancel.
