It'd be super neat if I could adjust the sliders shown in Color Editor boxes with my mouse's wheel or a scrolling trackpad gesture. I could understand disabling this functionality if the sliders were in a scrolling list to prevent accidental changes, but since there's nothing else here that's 'scrolly' I feel that there's no harm in adding it. Windows sliders have this capability as do those in other applications. It would be a real fluid way of adjusting color options, I'd use it.

(Horizontal scroll support would also be great!)
