Selecting points the way Illustrator does with Anchor points and its direct selection tool enables modifying existing sketches much faster. This would apply to edit profile sketches, model and detail lines, point elements and editing spline Control Vertices (CV's). E.g. hold the right mouse button to enter direct selection, drag over the points to select and edit the geometry by the selected points instead of by the lines. Joined lines (when snapped by end points) currently behave as two individual points, editing only works by editing the lines themselves, if they were joined it would be much easier to create skewed sketches. It would omit several actions.
