The new "Footways" category (under Transportation -> Walking) shows sidewalks, footways, steps, platforms and pedestrian zones. Sidewalks mapped on the street way (sidewalk:left, sidewalk:right resp. sidewalk:both) will be shown with an offset - hatching indicates the relation.
If you have an questions, comments or ideas, please create an issue on Github! Quite some new strings were added to the translation system. Your participation is highly appreciated!
