Are you able to expand the mixer window to a bigger size on a 24" monitor, so on could view all mixer channels at once without scrolling?
We designed the GUI to fit on a 13" laptop so it didn't hang off the smallest screen estate windows etc. Scrolling was one of those compromises.
However, if you haven't spotted it yet, using Command+1 (Analogue inputs), +2 (Digital inputs), +3 (DAW playback) or +4 for System Panel will allow quick access to all channel view modes (useful shortcuts). In typical use with the system panel shut, you can see all 10 inputs, DAW playbacks likely hidden for recording once you have checked you have signal for cue mixes etc.
This should be faster and quicker than scrolling or using a larger mixer GUI.
