I noticed the TG waypoints are building a binary file.
Also, under both the Path Tab for roads and when using the beach tool, Shift+Left click adds a point at the end of the path. Perhaps Shift+Left click could also add the next Waypoint under the Task Groups tab.
The Add Point button would become unnecessary as the CV will always be the starting point for the waypoint list.
Also, shouldn't Ctrl+left click allow you to edit the previously set Waypoints?
