Hitting F11 works beautifully for me. The UI is very clean. I like that it isn't too wide. If that's what the original poster meant, then I'm not sure that it's necessary. I would make at least one UI change though: make the page scroll smoothly and earlier than it currently does. Right now the box you write in extends down as you type long passages, until the text you are writing is literally pixels away from the bottom edge. At this point, each line is written at the very bottom of the screen, which is somewhat awkward, at least on my laptop. In addition, where in a typical text editor or word processor one can scroll until this text is at the top of the screen and then continue, because the text you are writing is at the bottom of a html document, the best you can do is scroll an inch or two down before you reach a blocking point. It might be very nice to coerce the cursor position to between, say, 20% and 70% of the way down the screen so that you never have to type at the far edges above and below, just as you leave space on the sides.
