I have a use case where I’d like to be able to introduce a handful of users in a visually compelling way in a post. I think it would be handy to be able to add e.g.
[usergallery]@user1 @user2 @user3 @user4[/usergallery]
or
[usergallery]@group1[/usergallery]
and have it automatically display a selection of users including key user card info like picture, name, title, country.
