Reena Jha from India shared with me on Twitter a new search interface being tested by Google, maybe only in India, I do not know. The new interface puts the navigation in tabs in the footer of the page. This replaces the hamburger menu on the side top of the page and includes a tab for home, upcoming, search, recent and then more options.
Here is a screen shot:

See the footer above, that is the new part of the user interface.

Pretty interesting, going back from the hamburger menu back to the footer tabs.
