So basically my suggestion is about adding a new feature (GUI or whatever) to manage your chat in-game.
Main Chat: Y or N
CC: Y or N
LocalChat: Y or N
TeamChat: Y or N
RadioChat: Y or N
Because for example if you're having a role-play and you'd like to focus your chat on the RP and LocalChat, then you can do it rather than having your screen spammed by other chat(s). Your chat will be only about that RP organized and easy to read for yourself and others as well when they see the screens of the activity.
Besides role-plays and many other examples, each one might manage his chat as he likes
I think it's easy to be done but what does the community think about it?
