Two months ago, we announced our plans to roll out a new design for the Google bar. Our goal was to create a beautifully simple and intuitive experience across Google. Based on your feedback, we realized there were some elements of the new bar that we could improve, and with that in mind, we’re introducing an updated version that we believe will provide a better experience.
The new design retains many of the feature changes we made in November that proved popular, including a unified search box and Google+ sharing and notifications across Google. The biggest change is that we’ve replaced the drop-down Google menu with a consistent and expanded set of links running across the top of the page.
We'll be rolling out this new version of the Google bar over the next few weeks. In the meantime, we invite you to read about the new design in our Help Center, and send us your feedback.
