Im telling you now... I am not the best at writing suggestions. but while you trade i think there should be a window by the trade screen and then u could type to the person you are trading with...Because in world 1,2,3 and all those big worlds where everyone is selling and buying and you trade, you put up lets say "X" amount of money for "X" item, you cant communicate clearly because there are like 100 other people yelling, "buying this, selling that"
