is it possible to add an option to the paint bucket that allow us to fill only the face we click on? Maybe include a "leak" slider to help it paint tiny pixel points that are almost hidden when dealing with slopes that are not at 45°.
About editing textures:
I havent tested this too much but.. When I tried to edit the texture with aseprite or event inside blender (with blender texture paint tool), it seems that when I go back to Pixel Art plugin to paint again, the previous editing with other tools "reset" or disappear. Any idea why?
