1.- I mostly wanted to suggest rulers, I own sketchbook pro and even though it feels ok to draw in it I don't use it much since It's quite limited for my taste, but it has some very interesting ruler tools that I haven't seen in any other applications and are very useful, it would be amazing to have them in a paint program like Paintstorm (it has a circle ruler that can be reshaped into ellipses, straight ruler and French rulers which are quite cool).
2.- The warp transformation tool would be really great as well as liquify (they are both important for my work at least).
3.- Ability to create different custom color swatch palettes (I didn't figure it out if it's implemented).
That's it for now.
