We got into this little discussion a thread ago about whether to make the address, button, status, and all other bars go away. Turned out to be simple enough to implement, although it only works if you're using Mozilla (finally Mozilla scores one over IE). Click the Settings button, and you'll find that you can select either "normal" or "bare" window styles. "Bare" means that you have just a naked window, giving you the maximum screen real estate, and also getting rid of the browser controls that aren't really compatible with the Nexus. Like the other settings, you can have the browser "remember" it using a cookie.
