When you're in a Mix, it would be nice if the top half of the scribble strip identified the Mixes (the buttons above the scribble strip), and the bottom half of the scribble strip identified the input channels (the buttons and fader below the scribble strip). This would make navigating the mixes mush easier during a sound check.
Currently on the CS18AI the Mixes are just numbered 1 through 16 without any names, so not easy to navigate. I have used tape and a pen, but it looks ugly and old school. In UC Surface they can be named, so identifying and switching between is easy. On the CS18AI I currently hit the Mix Masters button to change the scribble strip so I can figure out where a mix is located, I then hit 1 - 16 to edit that mix. However once I'm in a Mix, I need to go back to the Mix Masters again to figure out where the next mix to edit is located. It would be nice if I could just look at the scribble strip and directly navigate from Mix to Mix.
