When we are 10 or 15 players on a server, it's sometimes very difficult to follow a conversation with an other player. When many players are writing, the messages scrolls too fast and we have no time to read.
So, I thought to a solution : multi-tabs in chat zone. One for the public chat. The others for private chat. Like in IRC. He just needed a command to open a private chat with another player.

Your opinion ? Suggests ?
