Hello (again)
[Micheal Caine voice] I've just had an idea [\Micheal Caine voice]
Given it seems common for OSM data to fail to mark Sustrans routes as bidirectional when differs from adjacent road, could you add a mouse-click option to 'override incorrect Sustrans way-ness to 2-way cycle path' which could then flag the problem to you are direct to OSM automatically...
Regards and thanks for the route-app.
