I love this breed of editor. Your implementation is pretty sweet, especially the quick save/email controls.

I'd much rather, though, just see a list of my documents than the too clever hidden dropdown. Right now it's two clicks and a three-key stroke just to open a saved document. Not so wabi-sabi.

And the word count is useful, but for "distraction-free writing" I shouldn't be forced to see it all the time.
