Wish - List already availlable values for a given key

[pl-gauthier]

I have this key value setup for people present in photos. e.g. people=mary,john,paul are in photo 2021-12-23.jpg. I was hoping to be able to see that "theses are are the people in the photo" and "these people values for the key people that are not associated with this file".

I know it does not make sense for keys holding vastly different values for each file. But I'm just throwing this here in the hope it would help the usability.
