That feature is still there. Everyone can create custom contacts in Phone account (to a limit).

Likely in a future update!

How do you mean the old layout? I haven't changed the layout in a long time..

You will soon. Some minor UI changes and it will be ready.

The beta went well for it so the functionality is there.

An emoji for an official account? Could you send an example please?

I didn't realise they change it. I'll remove the shadow soon.

Already possible. Use the Browser account and go to wikipedia.

Possibly in a later update
