Really great!
Thunderbird is useless without this add-on.
But support for Send later is urgently needed.

This review is for a previous version of the add-on (0.9.12).

Tag Toolbar immediately became my favorite and the best helper at work.
Unfortunately, tags are lost when I use the send later function.
