If you've ever wondered where your visitors were going on your site, you need this..
From the site:
This little plugin will store each click made on pages of your site in a database, and from there, you’ll be able to go to your blog’s admin section and view the various pages. See what is popular with your visitors and what’s not. It’s had some interesting results on the sites I’ve run it on so far, and wanted to share it here for people to download and play around with.
