New D.I. Feature - Snap Preview

I've added a new funky script from Snap which lets you hover over a link and you get a preview of the page that is linked. It seems to be really useful, but may become annoying. What to do you think?

If it becomes annoying, you can turn it off. While a preview is up, click on "Options" at the upper right corner of the window, and you can disable it for yourself.
