1. It's an alright idea, I'm neither for nor against it.

2. This, this should really happen in my opinion. Public chats usually get flooded with private conversations of 2-4 people all the time, and sometimes its very irritating, especially if they speak different language. This would solve many problems, and make chatting more convenient between clan members (or just friends)

3. Would be convenient, probably a bit too difficult to implement so i doubt it could happen.

4. There's already that sort of thing in game if you play on Steam, if you just do Tab+Shift. The complexity of implementing browser inside a game is so massive that it would never be considered.

5. This suggestion goes against the board rules so just forget it
