Great work! But I had some trouble getting it to run on my Mac.
I think it might be because I use VirtualHostX - http://clickontyler.com/virtualhostx/ - which alters my hosts file. I had to create a host - http://dotjs/ - pointing to my ~/.js/ folder - then edit the Extension JS to point the Ajax to http://dotjs/ instead of http://localhost:3131. A bit of pain but it might just be who this affects.
