create, delete vertex with (command+click)
You can create, drag, store and delete points, lines, polylines and polygons.
All vertices (of the currently edited polygon) now have locators associated, so you can drag them and place them separately with the mouse. Also, you can create and delete a vertex with a single mouseclick.
A host of options is provided (see details text).
