Rated 4 out of 5 stars

I use the tool a lot - very helpfull.
One important feature I am missing:
The rules are always based in the inbox. Rules for mails I sent (I have an bcc for all mails int the inbox so I am sure it was really sent out) always use the sender (which is me) as base for the rule. As a result:
Whenever I archieve a mail I sent the rule is proposed to all other mails I sent. So each time I send a mail to a new person I manually have to change the rule.
Proposal: if the sender is myself, use to "to/an:" field as basis for the rule.

This review is for a previous version of the add-on (0.2.2).
