1.Availability of Multiple "Track Colour Schemes".I've seen people making use of Colour gradients to improve the workflow.IMO the user interface adds to the creativity.
I have made added artistic Colours to represent my tracks, and i have added it into the auto colour feature too. I wish if someone could create colour schemes like these which the user can toggle (just like one can toggle like the UI themes )
Check this link and you will get a picture of what I am trying to say
