I would really like to be able to separate all of my private chats with different people so that I can look only at a conversation between me and that other person via a drop-down menu or something like that...
ex. if I'm looking for something that someone told me yesterday, like how to vote I wouldn't have to flip back through 15 pages of random chat with everyone to find it. I could just select for the Private Chat and click 'Mr.Burns' to see all of my chat with that one person instead.
