Allow the user to prevent creation of polygons (closing a loop) when drawing lines in Dooley.
When I am drawing an object with a series of points the software always wants to add a line from the end of my series, back to the beginning. This creates a closed loop or polygon. Generally the user doesn't want this and when it occurs over and over again it gets very frustrating.
Perhaps holding down a button such as control could over-ride this feature.
