ceate free user-points

Free user points are to be created and automatically collected in a list. A button creates a new point in the P column of the spreatsheet. The point is created in the first free table position of column P. Its default value is close to the button that creates the point. As long as the point has not been moved, it is marked with a red circle. The created points can be freely moved or deleted. The values of the points in column P and the names of these points are recorded in 2 separate lists. The index of these two lists is synchronous.
