As previously anticipated, Google tests a new navigation bar that could replace the black bar. Guao.kh has some screenshots of the experimental interface and there are three important changes: the black bar has been removed, the list of Google services is now a drop-down next to the Google logo, while the tools menu, the notification button and the sharing box are displayed next to the search box.
The new interface is cleaner, but hiding the list of Google services will make it more difficult to use. A lot of users won’t be able to switch from Google Search to Gmail, from Google Docs to Google Reader if the navigation links are no longer displayed without performing an action.
