I am using the GP with 13 inch touchscreen which allows me to do quick changes on rackspace buttos annd knobs. Also I would welcome a possibility to have a setlist button which will open the actual setlist in big window and big text easily rollable on touchscreen.
At the moment if I want to jump to another song than prev or next, I have to choose on the ledt side of the window, but the text is really small and not easily selectable on touchscreen.
