This was exactly it, thanks @Moin!
I agree with you, and at the same time it’s inconsistency UX to display most as name > username > title, and on seemingly random (to the uninitiated of this feature) not show some usernames and it just be name > title.
I’m glad this feature exists for my use case! As usually, just showing how incredibly malleable this platform is to one’s needs in customizing their community.
