P: Gradient editor needs a few improvements
It is almost impossible to use the gradient editor to simulate blending between lights, because it draws a straight line through RGB space. It would be good to be able to select HSL and LAB colour spaces for the gradient editor, and it would be even better if you could make bezier curves through RGB space, like the free tool at http://www.foddy.net/2010/10/gentle-g... is pretty frustrating that there was more flexibility in Deluxe Paint IV's gradient tool 23 years ago than there is in Photoshop's gradient tool now.
