Burp Suite Community v2 and the SpyDir Extension

Has anyone tried using the SpyDir extension for Burp v2? Specifically, I’m using v2.1.02.

This is exactly what I was looking for, but after installing, there is no trace of SpyDir anywhere except the Extensions tab. I’ve never used a Burp extension, so I may be overlooking something simple.

Has anyone been able to use this extension?
