Where you can't subscribe an address book in Thunderbird to a CardDAV server this is an excellent alternative. It would be EVEN better :-) if you could right click a contact and opt to add to an address book in a context drop down.
Thanks for the work you've put in.
Thank you for your suggestion and I will include that feature in the next version.
