[From ryanilg] It would be great to have a (javascript) confirmation before allowing the user to navigate away from a create or edit entry page, if content has been enter or has changed.

I have lost quite a few changes by accidentally navigating away. Since the editor does not use a standard text area, text is not retained when you switch pages.

I personally have "swipe back and forth" enabled on my mac, and I am constantly loosing edits.
