It would be nice if if the wireless app had a tab for simple one click preset selection/switching. Especially for CAB M, since there are no foot switch or midi to quickly switch preset in a live situation.
It is possible to change preset by swiping on the blue screen of the preset window (where the name is shown). If you swipe the name, you will change the preset. I have forwarded your idea to the software team to see if something could be implemented in the future.
