I'm in Ss2 and when I display a template, it uses individual lines instead of closed shapes. I do not believe it always did that, but I may be mistaken.
Anyway, since as components they are either open or closed shapes, why can't the display template tool preserve that?
And the drafting note annotations place the arrowhead at a centroid of the component (at least that seems to be what it does. Is there any way to have it do something different if the centroid is no inside the shapes? This seems to happen when the roads have a crown.
