@markus-kramer This is already part of our official roadmap. It will come to DAVx5 in a more basic form but probably not via a notification. But no ETA yet.
Support for syncing multiple address books
Please add support for syncing multiple address books instead of chosing between them.
I have one address book for all users on the server and one personal. So chosing between those is not what I would like to do…
So in short: please make it possible to sync address books like the different calendars.
