Doesn't everyone's menu bar go away sometimes? I haven't figured out how to do it on purpose, but it does completely disappear while I'm surfing the web on Dolphin. Well, at least sometimes. I've had the entire screen dedicated to the web page, no notification bar either. No tabs. But, I don't know HOW to make it happen, it just does - sometimes. Then the menu and/or the notification bar comes back. So, I think this would be easy to make happen with a software tweek.
