Google recently announced that they would extend “instant preview” in order to make video searches faster and more interactive.  The idea is to let viewers spend less time searching and more time watching videos by including more information during the search process.  Users just click on the small magnifying glass to the right of the search description in order to see a pop-up with more detai.  The catch is, depending on your browser, it might be easy or not so easy to enable instant preview so that you can see the magnifying glass in the first place.
