Review for CardBook by mdo1
Rated 5 out of 5 stars
An excellent address book replacement tool with much more functionality. Perfect integration with CalDav & CardDav backends (we use SOGo & Nextcloud).
A very active and responsive maintainer. A perfect example of a quality add on.
Ha, I just realised that I wrote a review already in former times (I wondered). It deserves it :-)
