When I group instruments, effects, etc. it would be nice to have in addition to, or instead of, 8 knobs, an X|Y control.
Also, could there be a setting where I could give the X|Y control focus and then use my mouse pad as an X|Y controller without having to use a mouse down gesture while moving the cursor (this would also scale the input pad to fit the control instead of using the system cursor to full screen scale mapping)? When I press esc or something, normal mouse cursor freedom would resume.
