If the mix channel buses are going to be this small, why are they forced to be spread out over 4 pages? It would be easy to fit at least 8 per page, but you could fit all of them on one page and allow user to scroll wheel if they don’t fit in the current size of the GUI…
Whatever size I have the GUI (sometimes stretched full screen, sometimes very small), there is almost always wasted/available space in the mix section for more bus channels.
The way it is now, it’s adding a lot of extra clicking.
Here is a mockup of fitting more in the space
