After one too many eggnogs I decided to make a long-planned addon. It fixes my pet peeve with Blender: that it can blend anything but itself. Now blender *can* blend itself. You’re welcome.
You can get the addon from here:
It can be activated from the Help menu (but you need to have a compositing window open) or from the compositor itself by pressing OS key(the one with the window, OS icon or other pic on it) D in the compositor.
Once you’re done blending blender, hit ESC. changes are not permanent until you save your user/theme settings.
