(Chrome Like) Auto-Hide Tab bar in Safari Full Screen mode

Is there a plugin or some other way to auto hide the tab bar in Safari fullscreen mode like the way Chrome does?

This is the only thing stopping me from using Safari, it's way smoother than Chrome and feels much more native to Lion, but the fact the tab bar just keeps hanging there is annoying.

I tried the Cmd+I method mentioned in the community, but it only works when you're only opening one tab, if you open several tabs, the tab bar will show up again. It also comes back up once you exit Full Screen mode.

Thanks for your help !
