Rendering waterway=drain, waterway=ditch, embankment, cutting and gully
It would be nice if waterway=drain and waterway=ditch were displayed in the hiking/biking style in LoMaps. They are very useful for outdoor activities. The same for embankment=yes (highway), man_made=embankment, cutting=yes (highway) and natural=gully. Of course, in suitable scales. For comparison, I send two places from LoMaps and in my style for OSM with QGIS + PostGIS.
