- Playlist title wraps within 90% of the width; rename and share are icons beside it,
and tapping the title opens the rename box showing the full name
- Offline, pin, select and delete are icon buttons to the right of the filter input
- Transport is one row again: prev, back 10, play, forward 10, next
- Update download stages each file as it arrives so a retry only fetches what is
