 You can reshape line and polygon features using the

 results. It is mainly useful to replace smaller parts of a polygon, not major
 overhauls and the reshapeline is not allowed to cross several polygon rings

+For example, you can edit the boundary of a polygon with this tool. First,

+add a new vertex. Then, cross the boundary and add the vertices outside the
+polygon. To finish, right-click in the inner area of the polygon. The tool

+also possible to remove part of the area from the polygon, starting the new
+line outside the polygon, adding vertices inside, and ending the line outside
+the polygon with a right click.

 \textbf{Note}: The reshape tool may alter the starting position of a polygon
 ring or a closed line. So the point that is represented 'twice' will not be
 the same any more. This may not be a problem for most applications, but it is
