Rated 4 out of 5 stars

It's a great add-on and I use for a very long time. However since upgrade to Thunderbird 115 this add-on conflicts with a Google Calendar integration and effectively kills the "Accept/Decline" Thunderbird buttons (I verified it by bisection).
It would be great if this could be fixed.
Beyond that - awesome thing!

This review is for a previous version of the add-on (4.1.2).
