Solo buttons in DAW and MIDI sequencers are aggravating.

Change them to have:

- Solo - only me
-- replaces other solo tracks previously chosen
-- can "undo" - which returns to last state
- Solos - add to other solos playing
... hovering over shows a list where I can check/uncheck now playing solos
- Regions on tracks can be muted/soloed in same way, marked with a button ON THE TRACK or just over/below it that region in the track. In this case the solo button becomes a different color or size, showing that not all is being played.
