You Should be able to Press on the name of the player you want to chat with to send them a private message. So you dont need to Scramble read amongst All the other people talking if you want to discuss strategy or such. Or/And make a private Chat room if you want a group chat with 3 or more.

If This is already possible and i just haven't Figured it out yet, i'm sorry for this Thread. :)

Another chat thing would mouse scroll wheel support to scroll up and down the chat log please ^^ (also scroll wheel to toggle 1>10>25>100>max crusader lvls)
