Rated 5 out of 5 stars

This is really cool! I've been using several extensions to hide my menu/address/status bars. This does it all. EXCELLENT!
I just wish I could assign individual keys to the bars (as I NEVER use the menu bar so I NEVER want to see it)...not just one key for all. Also if it could autohide bars on mouseover that would be just icing on the cake.

This review is for a previous version of the add-on (0.4.3). 

Individual key binding/Autohiding

These features were already on my TODO list :D
