Some touch interface tweaks/improvements would be nice. Mostly it works now, but the dials in the editor don't really work very well with my touchscreen. kinda just goes all the way up, or all the way down. (I use a surface just for my kemper because my main PC has windows 7, and I have no other need or desire to upgrade it, and I would rather not have two keyboards/mice at my workstation.)
A minor frivolous thing, but it would be cool.
