I always have just one CC lane visible in the MIDI editor at any time. To switch between my often used CC-lanes I've set up a bunch of toolbar icons.
At the left of CC-lanes there is some unused space. Since this area is very close to where CC-editing takes place, I figured it would be nice if I could have my buttons there instead.
Here's a mockup of what I imagine:
This would enable quick switching between your often used CC lanes.
