Initially I did not implement it because the Play-Test Applet is not suitable for specifying a variant with Shogi promotion: the order of the piece definitions is critical in that case, while the Applet inherits the order from the table of available pieces, without any interface for re-ordering them. But now that Diagram specifications can be pasted back into the Applet, this has changed. I guess I should make the textbox in which the HTML for the Diagram appears when you press the button editable. Then users could re-order the piece definitions there, and paste it back. Or perhaps there should even be a button for reloading what is in that textbox.
