Love the program. Still new and figuring it out though. Is there an extension you can save a GIMP image as that will retain it's history? I know Paint Shop Pro had that ability and I loved it because I could save one file and have all the different things I'd done to it saved at the same time so that when I opened it up I had the original image and all the work I'd done to it saved in one file.
If not a way to do it in the program, is there a plugin for it perhaps?
