I just had an idea for doing an actual animation. When I went to implement it in the animation editor, I discovered that it's missing a key feature...

Copy and paste among frames and to/from other applications.

I certainly wouldn't expect to hand-draw every single frame. Without copy and paste features, I wouldn't even begin to know how to get a really nice animation done.

I'm not asking for the complex task of region-selecting and copying/pasting selected regions. I mean, just being able to copy a whole frame to the clipboard, paste it into Paint Shop Pro, work on it there, and paste the edited frame back into the animation editor.
