One small criticism: In my opinion, no web-based writing app is useful unless the tab key inserts a tab. The default behavior of most browsers to move focus to the next field is tremendously infuriating in this context. Unfortunately, that's what happens here, at least for Firefox.
(Related: key combinations that normally perform cursor movements but which are often used by browser for navigation.)
