At the moment Rig Manager 3 can already be used with touchscreen in the most parts (like finger scrolling through the performances) but there is one big problem: The dial knobs in the editor section.
If you touch a dial knob and move your finger for just millimeters the dial knob will switch between highest and lowest value.
This makes the editor section mostly unusable on touchscreens.
Please consider this (I think small) fix. Being able to use touchscreen devices like windows tablets or convertibles makes it much more easy to use the editor "on the fly" like in a rehearsal when you could make changes on a dial knob with one hand while holding or playing the guitar with the other.
I am speaking mostly for Stage users which don't have the hardware knobs near them. But making the editor more touchscreen friendly and therefore more compatible for tablets will increase its use cases and easy to use.
