I just lost a post I spent an hour writing because I clicked on an image in my post which loaded the image, and then pressed the back button to get back to my post --- but it was nowhere to be seen >:|

Up until that point it was great, but if stuff like that happens its not quite ready for prime time. I'm sure that can be easily fixed with an auto-save feature that automatically saved the content to disk (or cloud) every couple of seconds after a detected change.

Just really pissed right now that I lost that post, but up until that point the editor was great.
