Rated 3 out of 5 stars

Coming from SOGO cardbook is definitely more reliable. Over the years SOGO connector had so many issues with sync silently failing, mysteriosuly vanishing contacts that later reappear doubled etc.

This seems to be way better.

However, the interface decission to have another GUI and the old one still there keeps confusing users, even when I take time to explain it, a few weeks they happen to get in the default addressbook and complain their (cardbook) groups are gone. It is just very unintuative.

Similar there is no option when writing an email, to address it to a group from Cardbook contacts from the Email Composer GUI. You have first go to Cardbook, select the group then click "Write To". Again altough it works, it is unintuitive. Again so much, that even user training is forgotten after a few weeks...

Biggest issue at the moment, there is thus no possibility to forward an Email to a Cardbook Group. It just doesn't work. Even Coping the Contacts and Pasting them into the To: Field, one would expect the Emails to appear, but no, its a list of Contact Ids.

Thunderbird and the wish to synchronize Addressbooks across devices keep to be an ever so frustrating combination.

This review is for a previous version of the add-on (15.7). 

Hi

the contact sidebar when writing emails will arrive in january I hope... for the moment, there is only the email autocompletion when you start to type... for the list not working, I will test but for me it works...
