Hi JJHaggar, thank you for this nice feature suggestion. Yes so a way to setup the brush like the shape, a gradient, then density and so would allow to do that. Noted for a future improvement of the drawing tool, thank you!
Implementing HD index painting and loading/saving effects presets as mentioned by Clovelt would make Pixelover an unmatched power tool for pixel art and animation. Hope to see these features soon!
