Thank you for your helpful work improving the map.  When you add sidewalks to the map, for example https://www.openstreetmap.org/way/337782565, it is helpful to also add the sidewalk=separate tag to the corresponding road, for example https://www.openstreetmap.org/way/255565308, as described in https://wiki.openstreetmap.org/wiki/Sidewalks#Sidewalk_as_separate_way
