You need to install both the Extension and the Plug-In... this was the only way to make it work.<p>You can write your own mini apps for any website using javascript. If you create one for a public website, send it to me and I'll put it in the gallery to share.<p>What do you think? Is it useful?<p>Should I make a Chrome version?
This is a pretty interesting concept. I like it! It's really well executed for being a weekend project. It'd be cool if we could integrate Google Analytics to it at some point.
