Wouldn't showing the seating chart in TD during the tournament accomplish the same thing? For example, during my tournaments, I show the seating chart every 10 minutes as i rotate the display between main -> seating chart -> main -> player rankings -> then to main again.
This is accomplished using a screen set.
I'm just curious why you need to print the seating chart changes since i like to see how others run their tournments and borrow the good ideas
