Rated 5 out of 5 stars

A beautiful app. Hopefully the update to Thunderbird 115 will come soon.

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

Thank you for the kind support!
I am working as quickly as I can and should have already been out already, but I discovered problems with Thunderbird mbox handling.
If you use it for other features, please track and download the latest beta here:

It's quite stable other than mbox support.
Feedback really appreciated!!!
