I like the fact that the robot tourneys make the human always declare now. But actually switching seats to make declarer at the bottom of the screen is confusing. At the table, one remembers that LHO preempted, for example and when you switch the seats around, it is disorienting. Can you retain seat positions? If you don't switch declarer's position, will one tend to forget which hand is "closed" and which one the opponents can see? I suggest that you change the look of dummy's hand, for example by using a slightly different color as the background for dummy ... In fact, changing the look of the dummy might be a good design idea anyway and could be carried throughout the software, regardless of whether it is a robot tournament or not.
