It does work well, but there are two things I think can be improved.
1. When you do a regular reply or forward there is an arrow that shows up at the beginning of the subject. It would be nice to have a similar arrow that means redirect.
2. When the person receives the redirected email, it does not say who redirected the message. That would be handy for people who use thunderbird at the office.
