Thanks Jo
I will make my changesets smaller and save more often with more descriptive text.
I do like this method "A different approach is to map each sidewalk as separate ways using highway=footway and an associated footway=sidewalk" as we have many streets without sidewalks, and some suburbs with just one or few footways, and it is best to render those that are present for cyclists, pedestrians and for the disabled in wheelchairs on the main map.
