Rated 3 out of 5 stars

Seems like great idea. However, the plugin do not have support for other than English language - it is OK to write a note but it affects encoding of email itself.

Secondly, the plugin makes my Thunderbird very slow - after removing, everything was OK again.

Good idea but needs some more work.

This review is for a previous version of the add-on (1.4.0.8).
