I'd love to see the ability to print (with the wonderful formating in-tact, and none of the interface) directly from my Gists. There are various bookmarklets out in the wild that attempt to do this, all of which are of course broken after this update.

I just had a need to do this with a bit of documentation I was writing. Ended up modifying the DOM to show/hide what I wanted and allow the screen stylesheet to be used in printing (to PDF).
