One idea I thought made sense is to set up one of the stand-in switches to move to the next "view". Chris on the forum here had a video that shows how this works. The idea is that when you're in a view showing three scenes, the stand-in switch would take you to the next 3 scenes. If you're looking at effects, the same switch would move to the next three effects. Then you still have another switch and two long presses for other things such as tuner, tap tempo, etc. That's a lot of flexibility with just a few switches!
