Installed Snap Preview Anywhere (SPA)

I've installed Snap Preview Anywhere on the site. I'm not sure if that is going to be annoying or helpful. If I get negative feedback, I'll take it off.

For the time being, if you hover your mouse over the SPA icon next to any off-site link, you'll get a popup JavaScript window with a preview of the web page linked to. Seems like a lot of web sites are using SPA these days; let me know what you think.
