I like the color coding that you can do to the player icons. I would like to to see two color tabs on each avatar. One on the lower left and one on the lower right. Most players recognize that there are two primary competing functions that comprise a given players game. One is the level of passivity/aggression and the other is the tightness/looseness of play. There are tight aggressive and tight passive players and I would like a color flag of each of those two factors.

I would also like it if instead of color tags, we would have the option to use letters or numbers, even labels or a library of characters.

It would be nice if we could assign the avatar to given players. I know that JoeSchmoe wants to be a Shark, but I should be able to set his avatar to display on my screen as a donkey, if that is what I think he is. He could continue to see himself as a shark as would anyone else that has not changed the avatar on their machine.
