Would that I had such a thing. My editing tools are quite primitive, consisting of a program called paint.net, which is similar to Microsoft Paint but with a few added features.

I can draw lines, squares, and circles, do cloning, cut and paste, pick and paste colors, and not much more than that. Hmmm... there is one more tool called "Gradient" that might be useful, but I don't know how to use it. Worth looking into, I guess.
