In the Analyst Client it is possible via the help menu, to see the users preferences.
It would help to be able to do this via the Web Player, as some users do not have or regularly use the Analyst Client.
To enhance this more, give it the ability to either find or filter the preferences, to make it easier to find the ones you are interested in.
Taking it one more step, you could also indicate which group the preference comes from. This should also be in the Analyst Client.
