Rated 5 out of 5 stars

I can only join the other colleagues, fantastic and very efficient tool. Worked perfectly by now. I am looking forward to seeing the update for Thunderbird 115 (and higher).
Wonderful add-on.

This review is for a previous version of the add-on (12.0.4).

Thanks for the kudos, support and great review!

I am actually fairly close with v14 for v115+.
I have a release tracker below that points to the latest beta. B6 is feature complete and well tested. B7 will have an important workaround for a TB mbox problem if you work with mbox files.
If you download please give feedback!
Cheers
Christopher
