(But the light green color makes the path to follow invisible unless I stop in the shadow to look at the PDA screen, which is not very convenient, it would be better in black)
I meant, on the website : when I view someone else's routes (or mine), I have to read the text or look at the red/green start/end markers to know which way the route goes. However, when the route makes a loop or a 8 or crosses itself, it is not easy to figure it out.
So, the little arrows should be added on the googlemap Route Planner, and the viewer, on the website, it would be useful ;)
