I was interested to read of the new online GraphHopper navigation facility in Locus Map version 3.25.0. I continue to use the add-on, updating the routing data myself from time to time. I had an issue with GraphHopper's Driving Directions at https://graphhopper.com/maps/ that I use on my desktop: the one 'Foot' option took me along vehicular roads instead of footpaths, yet the GraphHopper add-on with Locus Map would direct me along the very footpaths I would choose to take. I raised the issue on GraphHopper's own forum, without success. Here is the difference: I choose 'Walk' with the new online GraphHopper and it takes me along vehicular roads; I choose 'Hike' and it takes me along footpaths, just as the add-on. I am extremely pleased with that result.
