Like it so far, some visual feedback would be nice
especially an column in the message list showing which (if any) folder is associated with this sender. Possibly an UI so you can inspect and maybe edit/delete associations.

This review is for a previous version of the add-on (0.3).

The SQLite Manager (https://addons.mozilla.org/en-US/firefox/addon/5817/) does exactly what you want.
