Add the capacity to add some new colors on the cables could be interesting, to set on a color the synth, another one the drums, etc. On pretty big projects, the bunch of all the black cables are compromising a lot.

I remember that before the blue version (so the grey and orange version), the Feature Request to the capacity of changing the colors of the cables was very supported (a thing like more than 1200 likes, so the highest at the time). I think the Next Version need this update.
