About
This small script adds a save button to the editor bar that allows you to instantly save the contents of the editor as a draft. Although this happens automatically every minute or so, now you can force it to save the contents whenever you want.
...and now you can also clear the saved draft with the touch of a button too!

Platform
Since this little 'app' is a UserScript, it can be installed as-is in Chrome. Firefox users can use GreaseMonkey and Opera users can follow these instructions.

Nothing but JavaScript and jQuery!
{site}/posts/{postid}/edit. Otherwise this is basically what SO should have had in the first place. Even works for new questions too. :) – Jeff Mercado Feb 21 '11 at 4:00
