Right now you can change the color for any Track/MixConsole Channel except for Input and Output channels. It would be nice to be able to change these colors too - especially for inputs. If for example I’ve got a guitar coming in on one channel and a bass on another, then it would be useful to set those channels to the same colors I use to indicate guitars and basses in my projects. Similarly being able to use Pictures on the I/O channels would also be useful.
I wonder why when they added the color & picture options someone thought they shouldn’t be on all channels? 'Cause, you know, it had to be an active decision made by someone to not include them.
