I am not sure what you mean by 'shuffling'. Something like in Chess960? The diagram just sets up the position that you specify. It would be hard for a general diagram to know what kind of shuffling is acceptable. (E.g. must the King stay between the Rooks? What if there even aren't Kings or Rooks? Or when there are multiple ranks of pieces? Or brouhaha squares?) And what should trigger the shuffling? Refreshing the pase, to re-initialize the diagram? Should there be a button for it, and if so, where?

It might be better to just start with the squares that contain shuffled pieces empty, and put all pieces in the 'hand' in the initial position. People can then first set up the shuffle the want by dropping the pieces, and start playing from there.

Of course it would also be possible to just embed a small JavaScript routine in the HTML page that does the shuffling in the way you want it.

BTW, I added a hidden feature to the Diagram. (This was really only for debugging purposed, and I am not sure I am wise to mention it. For people might take it serious, but they will probably discover it anyway.) When you click the 'move' header in the piece table, the column toggles to display the piece values estimated by the AI instead of the moves in Betza notation. Don't believe them; it makes exactly the same errors as most people do when guessing piece values!
