[FEATURE] OSM way/relation tag number as a sign on buildings

[unquietwiki]

I'm not even sure this is possible, but maybe there can be an option to put signs on the buildings with their OSM way/relation number for reverse lookup. I say optional in case of privacy concerns, and/or computational cost required. From an aesthetic viewpoint, I'm not sure if the number should be on the top or side of the building. May need to prefix the number with W or R for way vs relation.

Thanks!
