It looks nice. Some observations. OSX latest chrome, firefox and safari.
Am I supposed to be able to change the subject? I cant seem to activate it so I can type there.
It's not immediately clear where im supposed to click to type the body, once it loses focus. Only feedback is that the mouse pointer changes. Once is loses focus, the 'message body' tag disappears making it even more difficult to know where to click.
Is it supposed to stay within a relatively small area in the center of the screen? I have a large monitor and tons of space around the sides. If you go all out, why not give people their entire monitor real estate? Actually, the original screen is much wider than the zen mode screen for me.
