there’s a shop that sells boards as in wood that comes out of a sawmill. You can get a pile of boards all from the same tree trunk. And they also have lacquer, hard wax, oil and such stuff.
How do I name such a shop in OSM? I’m using the online in-browser editor.
I don’t recommend shop=wood because it’s too ambiguous.
Most of such stores are tagged as shop=trade + trade=timber;wood_finishing_materials
