Hi i would love for a feature like this to be added, basically this is kinda my idea:
A friend system that you can send a friend request from right clicking in the player list;
where adding someone as a friend makes it so you can join their server from the beam ng server browser friend list wich could be located in a button on the left side;
when ingame their name would be green in colour and in chat also, on wich you can switch the chat to “all” or “friends”
probably it has been already asked or discord has been deemed enough tough i would still like to share this idea.
