Hi Len,

it conflicts with gestures, if you by accident don't touch the control
and you do the two finger pinch, something unpleasant could happen.

IMO
1 touch the control, it gets a colour that signals that it's activated
2 put a finger some distance away
3 move towards control to decrease value or farther away to increase value
4 touch the control again, to deactivate it, colour becomes normal

Regards,
Ralf
