Continuing the discussion of the Insert Node(s) tool from:
I changed a routine in the selection of nodes so that now you can select the start point of a curve, the curve, and points on the curve, and it will automatically append the curve after points on the curve OR select the start point, point on a curve, THEN the curve… and it will also automatically insert a curve node before the point on the curve. In other words it doesn’t matter the order you select a curve, or a point on the curve EXCEPT if you select multiple points on the curve, in which case a curve will only be inserted for the point preceding the selected curve… unless I can rearrange some code, in which case it may work with multiple points. 
That being said, there may still be cases where unless one sticks to the clockwise selection order, the curve auto reverse may not work. Which to be honest I don’t see as a big issue as 1) A user has to adhere to the clockwise order when Adding a piece in the 1st place. 2)A user shouldn’t have to rely on inserting a large number of nodes to create a piece.
Also, this update will render an issue moot that Susan created regarding the current Insert Node tool, where the dialog sometimes pops up with an Unknown node. The multiple selection uses a different logic that ignores unknown nodes.
