Introduce a feature that lets everyone see who's in the contact list, but only lets the assigned user/s peek into the actual chats. This way, everyone knows who's around to chat with but doesn't crowd into conversations they're not part of. It's like having the guest list to the party without overhearing all the conversations – keeps things private where they need to be, but still lets you know who you can reach out to. Plus, it keeps the chat space tidy and makes sure only the right eyes see the right stuff. Kinda cool for keeping things both open and on the down-low, right?
