I used to use FL Studio, and it has monochrome, smaller icons that very cleanly describe, without taking up too much space or looking awful, the tracks' content or purpose. You could number tracks outside of the "rename" function, denote which side of a stereo channel the track was for, identify busses (FL Studio's routing is freeform), show whether a track is a kick, snare, hihat, guitar, saw wave synth, keyboard, plugin, anything. And, since it was monochrome, each icon could take on a shade of the track's assigned color, making organisation that much easier.
I'd love to see something like this implemented, especially given the limited space in Studio One's console and track controls. It would fit the new look in v3.x and be very easy to get used to.
