This might be more a donator feature, but it would be nice if GM's could tie a given dice pool to a player. This would allow the GM to do things like removing natural 1s/20s, changing the probability of certain rolls (favoring one end or the other, or perhaps a number in particular), and so on. In order to work properly, this would have to be a GM-ONLY command/option, and only visible to the GM. The player should have no idea that their dice pool has been affected. This may seem unfair and completely stupid to players, but fellow GMs know full well the pain of a player who seems to always roll low/high. Plus, this lets you spite "that guy."
