If you are interested in adding sidewalks, our Pedestrian Working Group has created a schema guide. I thought you might be interested with all of the sidewalks you added. Can you look at the street crossings? they should be tagged as highway=footway + footway=crossing. There are additional tags for marked crossings. 

Let me know if you have any questions or would like to be more involved mapping pedestrian ways.
