Rated 3 out of 5 stars

Hi, nice add-on! I think that you can remove the status-icon in the bottom left: leave all add-on settings in Tools->Add-on dialog.

Another feature that would be useful is to have the retract options in right-click menu on own sent-emails, and not only in sent-email folder.

Regards

This review is for a previous version of the add-on (0.9.26a).
