Google Quick Scroll now integrates with Instant Previews, so you can click on a highlight from Google's screenshot to be magically taken to that part of the page. It's a lot faster to find what you're looking for, especially if you have to scroll to the bottom of the page.
Google's previews are now available for Microsoft Office documents and presentations. There's also support for Flash, so you'll no longer see a puzzle piece image instead of a Flash object.
