Just to put these here as well.
-Ability to colour by "note pitch" (repeated per octave). This might not be possible but being able to see each note in an octave as one of 12 strongly defined colours that repeat each octave would be insanely useful for editing and easily seeing pitch of notes etc.
-Presets. At least at the global and maybe make them action assignable for the first 5 of them. These would be great for getting the most optimum view for say individual types of instruments as well as an overview.
