In this user story, we plan to allow the user to visually see the sequence numbers when a VF module is added from the left panel of the drawing board onto the right one.

This is only about the default sequencing that the drawing board renders when a new VF module is created into the 'instance' part of the drawing board from the 'model' part of the drawing board.
