Not even PhotoShop has, by default, over 500 levels of undo. I have been looking for a program like this for years, I had all but given up. Life was becoming meaningless. This program may have saved my life.

I sent you 5x the price, and it was worth it. Thank you thank you thank you.

One note: please do not succumb to feature bloat like all your (inferior) competitors and add other stuff like nose hairs. That belongs in its own program!
