A fresh thought on the topic... Since no developers responded, this is only a workaround:
OSM supports tag information=guidepost. OsmAnd allows to save custom category: guidepost (matching official OSM tag) + name has "trailhead". Let's start adding "guidepost" to trail heads, plus name containing trailhead? How does this sound? -- You received this message because you are subscribed to the Google Groups "Osmand" group.
