Grey and old ts wise man speaking: back in the days of old we used to have such a feature. It died with a forum update. Best to ask the founder about this.
Also I would be interested in a way of looking at forum statistics. I mean aren't we stats geeks? How about some functionality that allows me to search for the number of Dason post as a function of hour of the day. Or detect which topics are trending at the moment or which topics trend in each university semester. Such features, limited to contributors or mods, would be pretty nice.
