New Google Navigation Bar Rolls Out – Social Layer Coming?

Google users may notice a new top navigation bar across Google search, Gmail, and possibly other Google services. 

Google’s statement: "Last week we tested a new top navigation bar, which increases consistency across most of Google’s properties and is a visual update over the previous top navigation bar. We are now rolling this new bar out widely."

Google’s Social Layer May Be a Toolbar

Update: A screenshot of what this toolbar might look like has appeared. Google of course says it is always testing features, and has nothing new to announce.
