When editing vertices you must double click the polygon to show the vertices, then hover over the vertex till the pointer changes to a "move" pointer before you can click on it and drag it to its new location.
Is there any way to set the tolerance on when the pointer changes to a lot wider then default. Currently you have to be precisely over the midpoint of the vertex before the pointer changes. I would like it to change just hovering over any part of the vertex. Any suggestions?
