What a nice idea. But it works only on Thunderbird 78 and only with TBSync which only works in Thunderbird 68. How is anyone using this right now? Is there a TBSync update for TB 78?

This review is for a previous version of the add-on (1.18). 

the update for tb78 has been withdrawn, as a user here reported it did not work.
