Rated 3 out of 5 stars

I have a dozen emails to communicate with different people, (and always send to the same person with the same From address,) and can't see how these colors can help me. I believe a better solution would be, the add-on automatically choose sender depending on the recipient (and the user can manually override when needed). That is, when sending an email, we fill in the To address, then the add-on automatically choose the sender. The "rules" of choosing sender from recipient can be determined by a form to fill, where one can use regular expressions or catch-all symbols.

This review is for a previous version of the add-on (0.9).
