I often find the changes I need to make to a channel's level are more related to its current level, than an absolute percentage change. I'd like to be able to set my +% button to /200 (double the channel's current value), and my -% button to /70.7 (sqrt(1/2) of the channel's current value). This can be achieved with macro keys, but it'd be handy to have that available right next to the main keypad.
Thanks for your consideration!
