The adjustment sliders are way to touchy, due mostly to the length. You display a number to represent the change, make that number editable. So if I want the contrast to go up 3 points, I can just type in 53 instead of trying to get the slider to tha

Sliders in the adjust tab, are about an inch long difficult to precisely manipulate with a mouse. a number is displayed that goes from 0 to 100. Make that an editable field much easier to nudge changes by typing in a change. It would also be helpful to have the type of change, i.e. brightness, saturation, etc. selectible so the keyboard arrow buttons can be used to change the values.
