Rated 5 out of 5 stars

Works great, but there is a bug where it won't automatically add the signature I have associated to the default account in the e-mail.

This review is for a previous version of the add-on (0.43pre). 

Hi Andrew,

Thanks for your review :-)
As far as the signature bug goes I'm not able to reproduce the behavior on my own 3.0.3-installation on XP.
Are you sure this add-on is what causes it? Could the behaviour have been introduced by another recently installed add-on? I'll be happy to investigate further if you provide info about your TB version and OS.
