In what seems to be an about-face from the adoption of the black left justified "Google bar" that currently lives across the top of all Google apps, the new version gets rid of the black background and moves to the right.
In my opinion this makes the Google+ link to Google Social Networkking platform even more obvious and seemingly relegates the useful links to: maps, Play (Google's app store), YouTube and more. To now reach these functions, you click on the three by three grid image, which then drops down the icons for these popular apps.
Will it catch-on and be adopted across the entire Google estate? Or have I just stumbled across a limited test by the Big G?
