As much as Chrome has been my favorite browser for Mac for a while now, with the release of Lion I've really been longing after some of the features of Safari - namely the well integrated full screen mode, and the iOS style zooming.

However, I can't stand having a separate URL bar and search box. This plugin seems to be working really well at emulating the Chrome omnibox!

(I have no association whatsoever with the development of this plugin, just found it by googling for safari omnibus)
