For a long time, I've had this idea of being able to use Ableton's piano roll as a musical score, where you can edit MIDI notes on multiple tracks from the same piano roll. So whatever track you are working on, you have the possibility to mark which other MIDI tracks you want to view (maybe a solo button aswell), and each MIDI track is represented by it's unique color.
So if you are working on the bass for example, you can choose to view the piano notes as well. This way, you can edit and get a nice overview of the tracks you want, just as a musical score in Sibelius or Finale.
From a composers work of view, wouldn't this be absolutely wonderful?
