Steps to reproduce:

Try to filter your address book for contact categories.

Actual results:

No categories supported. The address book is just "flat".

The only way to categorize contacts is to create multiple address books but then I can't have some contacts in multiple address-books without having to create duplicates.

Expected results:

I would like to add "labels" or "categories" to my contacts. Also allowing to display a "grouped by category" view to the address book view so I could divide contacts into multiple groups like...

• business contacts
• personal contacts
• ...

I know I can create lists but lists don't even link the address vCard but basically manage an independent entry which is bad as if the original entry is updated the list is not updated.
