Here's my use-case: I'm doing a pixel art sketch, and one of my layers involves glass with partial transparency.
I'd like to be able to:
Eyedropper the transparent color and have it automatically take on the eyedropped transparency value
Paint with that color absolutely, not additively. Clicking should make that pixel that color, not ADD that color to that pixel.
Anyone have any clues for me to get either of these to work?
