I used to easily specify a color for light tones, a color for dark tones, and the balance between them, all with a few easy-peasy sliders, and after a single afternoon's practice I could get the effect I wanted every time. NOTHING WAS WRONG WITH IT, SO WHY DID YOU CHANGE IT??? Now I fight with these unmanageable circles, and no matter how I try, I consider myself lucky if I get even a remote resemblance to my intended effect. I told myself I'd get used to it in time, I'd learn it with an afternoon of practice like I did with the old system, but no--it refuses to work for me at all. Please put it back, and stop changing things that work just fine. Change for the sake of change is insanity.
