This is updated with some of my latest icon additions, so unless I've missed something, all that's left is to figure out how to make promoted pieces demote upon being captured (if that's even necessary). Then I can move the Diagram into the main article, and it'll be ready to go.
Setting holdingsType=-1 in the Diagram definition takes care of these types of demotions automatically.
Also, you say promotion is mandatory upon reaching the last row. Does this promotion rule apply to all pieces or only to Pawns? If the former, does it also apply upon leaving the last row after a drop?
