Google Has A New Interface
Other than Google+ project, Google has another improvement for their search engine. A new experimental interface for Google’s results pages was spotted. The most obvious change is that the navigation bar, the search box and the search options sidebar stay at a fixed position.
With the new interface, you do not need to scroll to the top of the page to find the search box in order to change the search keywords. Pagination is removed and the stage is replaced with infinite scrolling like what used by Google Image Search.
There is also a new user interface for Instant Preview. The button appears to the side of the result text preview instead of to the side of the result webpage name. You will need to hover over the magnifying glass icon to pop up the preview.
