I feel like the chats can get a little crowded or awkward when they have more than just two people in them. It would be nice if chats with more than two people showed the name of the chatroom instead of the names of all participants.
@v4 I think there´s already a plugin that lets you do that, show the N last posts from a category in the home page. Since you only have one category, i think that meets your requirement. Check the plugins category in this forum, i think you'll find it there.
