Ooh it has the tabs on top for OS X now. Will take a look at this later.
I've been looking forward to this for a while - between safari and chrome and ff, there really isnt a faultless option on OSX.

I upgraded from 4.0b1 and my awesomebar does not display a thing when typing something in. I have checked the preferences and that is all fine and dandy.
Disabling it makes awesomebar work again
