Rated 5 out of 5 stars

Fantastic! I can't belive this isn't part of the Core or at least a permanently recommended AddOn!

My dearest wish would be to also have Categories (as e.g. the AddOns 'MoreFunctionsForAddressbook' and 'SoGo' add these) displayed and editable. To reuse the multiple choice form field code of Firefox' bookmarks would be most elegant, i guess?

Second, i often want to have a temporal sorting (think of "latest" or "recently active") at hand. For the first, CardDAVs 'last time edited' timestamp of each contact comes in handy.
(The latter need more work, including some requests for conversation statistics...)

This review is for a previous version of the add-on (2.6).  This user has a previous review of this add-on.
