It's probably poor form to comment, but google finally indexed this little site here and I'm kind of excited about it. It's good timing as the 0.4.2 release is really the one I'm most confident in so far. At the same time, I have the extension submitted to mozilla's addon site so hopefully that will go through in a week or so.
As always I'd really appreciate any feedback. If you don't know what sort of things to tell me, just drop me a line telling me that you'd be happy to talk and I can throw you some questions that would really help me out.
