How to Get Out of Contacts App's Lists?

When you tap on All iCloud it displays all of the contacts in all of your lists. If you tap on a specific list it will show just the contacts in that list. That’s not an editing function, it is just a view of all contacts. You can tap on an contact to view it, or once you are viewing the contact you can tap on Edit to edit the contact. Or just tap on a phone number to call it.

Tap All iCloud. Here’s more information on Contacts→iOS 16: Redesigned Group Management in Contacts- Apple Community

I think you only see the Done button if you edit a contact. Just tap on the All iCloud to get back to the entire list of contacts.

Ah, I understand now.

“All iCloud” is one of Lists — the superset list.

Well put!
