I would say that it is about time to add a messaging system to the friends menu. Sometimes it could come in handy to send a private message to a specified player.
It could also be a new messaging command added, like on Hive Java:
/msg [player] [message]
The player you are messaging should have to be your friend to prevent message spamming.
I would love this, unfortunately Microsoft’s rules are strict, and don’t allow private messaging (1 to 1). However, they allow 1 to 3, for example. On java, it is possible but on Bedrock not.
