I would like to have a option, that is present in Mocha, to quickly Enable/Disable Gamma and Gain settings.
Sometimes I set the gamma to better view an area to paint.
While doing this I occasionally need to see it in its original form (without Gain and Gamma edits) and ideally, I would just pick a button (or keyboard shortcut even better!) that will Enable/Disable that correction for a second or two.
