Coords of line origin (and vertices for flower trails)

[Thortok]

Some way of displaying the origin coordinates for lines (either when mousing over the line or perhaps as a second set of coords on the popup) would be handy.

Flower trails might want to list the coordinates of every flower in the trail (again either via mousing over that spot on the lines, once that feature is added, or as a list of coords in the popup).
