I was thinking about this recently.
Wouldn't it be cool if ZOS some how managed to implement a pickpocket system in-game. Whether it was just NPC's or something. You didn't have those materials you needed, you could always try and pickpocket them from the Enchater in Daggerfall. At a price of course. Who doesn't miss hearing "STOP! You've violated the law!". This is clearly not a incredibly tangible idea, but I think that it would be a pretty cool edition because I sure do love a good pickpocket.
