Addressbook-Filter in Contacts

Hello Community, hello Developer,

I do not organize my contacts in groups, because I use different address books. What I’ve always missed in the Contacts-App is a possibility to filter contacts by address books. It would be best, if the address books were listed in the left menu. So the contacts could be listed with one click. I think this feature would be practical for many people.

Best regards,
