Hi,
I think that it would be very helpful if the ‘Start’, ‘End’, and ‘Join’ buttons of the ‘Line Tool Properties’ were available within the ‘Contour Editor Options’.

EDIT:
I even think that it would be great to have these buttons within the ‘Cutter Tool Options’. It would be handy if one could select an edge and change its tip shape without having to switch to the Select Tool.
