With accounts being "cryptic" keys, recognizing follows or people in general is hard in nostr as users can change their avatars and nicks, including to those of other users.

Client devs please allow me to define avatars and nicks of my follows (and ideally to annotate people).

I want my client to copy the current avatar and nick when I follow somebody. Whenever a change is detected, ideally checking the avatar's hash but url is ok for a start, discretely mark the avatar/nick so I can accept the change, ignore that change or chose to never change to their chosen profile.

The client should also allow me to override completely avatar and nick of any profile.

I want to store notes about profiles. "met at BTC Prague", "works at trezor", ...

All the above should be in private/encrypted lists.
