Yeah, that option would require a new API and work done on the OSM server to both calculate the last time a tag was edited, serve it and store the timestamp when "touched" or updated. But once that's done it's done for multiple clients, not just StreetComplete. Otherwise StreetComplete would need to use the History API one each individual nwr and try to calculate the age of a tag. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
