So Chrome updated to ver 26 today, and I took notice that the menuing had a distinct "Metro" feel. The Menu's have that traditional "Metro" spacing to it, and as such, seems to "complete the feeling" for Chrome to be a fullscreen Metro App.
It also has a new "Restart Chrome in Windows 8 Mode" that restarts the Web Browser in the Metro Fullscreen mode. It's kind of nice ![:D]()
(And for the curious of the Facebook redesign[it's what happened to be opened at time of screencap] it is NewGenBook 4, a very excellent Chrome addon.)
