Anybody keen and know how to change the headland drawing page?
Maybe @KentStuff had something in the tree version thats halfway there? (I remember something about tree lines intercepting the boundary or headland line and droping trees on that point)
Currently you can draw a headland even distance off the boundary, and if you want to move a section its not very clean.
It would be nice to make lines off the boundary at any distance needed (Just AB lines or Curves) then select these lines and where they intercept make points and draw the headland off only these points.
