The sketches are recognized based on shape rather than other features requiring a particular stroke order or direction to provide the maximum amount of drawing freedom.
	Because we are working with digital ink, the sketches can be edited.  Because the sketches are recognized, the drawn objects can be naturally moved as a whole, affecting other objects as appropriate.  For instance here we drag an object and the relationship stays attached.
