Why doesn't freehand ployline and polygon snap while drawing?

Discussion created by btfou on Aug 23, 2013
Not being able to snap, at least endpoints and vertices, limits the usefulness of these tools.  For example, drawing a freehand ployline with endpoints at two points requires the user to "get close", and then edit geometry.

Even better would be edge snapping, as to mimic trace in ArcMap.

Whatever the reason, it would be a great upgrade in functionality.
