Ok, I just had a thought... are there any screen capture programs (for any OS) that instead of emitting an image, emit a (Photoshop|Gimp) file with layers for each discrete UI element (Window, Toolbar, Dock, Mouse, Menu [for a mac], etc.)? It would be cool to open up this file, and be able to drag windows around, and re-organize a screen-shot, just like moving windows around :)
I'm not sure how much actual *use* I'd have for something like this, but it sure would be nifty!
