A new grip option, Extend Vertex, adds a new vertex to your polyline extending from the selected end grip. You no longer have to reverse the polyline direction.
The existing Add Vertex option could add the vertex between the end and the previous vertex. It depended on the direction the polyline was drawn.
With the new Extend Vertex grip option, the vertex is always extended from the selected end grip, no matter which direction the polyline was drawn.
