How to remove/hide the Navbar on Mojo? topic

Hey again guys. I've been doing further research and I'm positive the console I want to buy next is a Mojo.

I plan to root it as soon as I get it, so the important question is: how do I make it so the navbar doesn't show up? Apparently its always present by default, making all apps even XBMC not actually fullscreen.

Hopefully someone can tell me that. Thanks!
