I'm thinking about making my own program that has all the ease of paint with more features such as being able to have a grid, zooming in farther, more undo's, animating, saving as different image types, a tile previewer, etc.
Just basically the perfect graphic tool for making sprites and tiles
Oh and the person saying psp/photoshop is like riding a bike compared to paint being a bike with training wheels.. that's only your opinion. I find photoshop and paintshop to take too much space, has too many crappy option I will never use, confusing layout, even more confusing with the stupid windows and such.
