I think a great feature for this program would be the ability to have multiple images open at once. This would also create the ability to split an image to R/G/B in different windows. Opening another instance of Paint.net can be a nuisance. It would be realllly nice to be able to switch quickly between pictures, like the way you can in Paint Shop Pro. Btw, excellent program. A really great beginning to what I'm sure will be a thriving project in the future as well.
