I would really like to see an Adventurers Journal Added to the game. Something that players can use to jot down notes, even stories about their adventures through out the game. It could be set to private or public so that other players interacting with them could view it if the player wished it.

The other suggestion is Biographies. Id really like to see biographies added to character sheets that could also be viewed by other players.

Give players the opportunity to tell others their characters stories and histories. I play other games where you can stop and "inspect" a player. Some of them dont show anything particular about a characters set up. But it does give the player the ability to read others biographies and its always interesting to stop in City Hubs and just read the random stories that appear. Even if we never interact.
