Expandable "More" Box

Another nifty little idea that Google is trialling on a limited basis, as found at Blogoscoped - go there for a screenshot.

This one gets rid of the Groups and Froogle links on top of the search box and replaces them with a link to Google Video... and when you click on “more,” you’ll see a box open up on the page listing a couple of Google services (along with an “even more” button).
