Give each track a visible number
As a performance artist I want to identify a certain track easily to memorize/make notes about the attributes of a track like instrument/MIDI channel and pattern type.
At the moment the only difference one can see in the track view is that each track looks somehow different. Or maybe not even that if some of the tracks are in keyboard mode. At least for me it is really hard to memorize what's behind each track. Therefore it would be helpful to see an unique identifier for each track of a song.
I think giving them a number which is incremented should be sufficient. As an addition, tracks which are sharing one instrument could be numbered differently like 1-1, 1-2 or 1-a, 1-b. The number could be viewed by holding a track or the audition button.
