not sure if this is an easy fix, but I did noticed something when I was replying to a post where I'd like to see something added. I was in the middle of replying to a post when I decided not to. The only options I saw then were either to "submit" or to "prevue." No button to gracefully cancel. I just used a link to jump elsewhere. Also, I have no idea what "autosave" does in this case.
