I made a thing (it's for tagging United Kingdom addresses in #OpenStreetMap and #JOSM)
https://josm.openstreetmap.de/wiki/Presets/UnitedKingdomAddresses
Feedback and boosts welcome
I think I like it for small-scale bulk correction of my bad addresses! Having it show a green (second class, lol) stamp for wonky addresses and correcting them via the dialog just feels nice.
Josm hates houses without streets tho, and doesn't know about addr:substreet. Somebody should totally report this to Java Open Street Map Inc.'s head office (or, maybe my local validator ignore addition will actually stick, idk)
