The operator tag is translated as an "Owner" which is wrong - there is a separate owner tag for that #9599

The height tag is used in the config, but not displayed in the editor UI (in android at least), e.g. for the waterfall type.

Some types are configured in the editor config but don't show up in the editor, e.g. man_made-surveillance, amenity=waste_transfer_station - should they be searchable / present in categories.txt for that?

Looks like there is no control in the config over adding social media links and they're added automatically when its inappropriate, e.g. for a dumpster/waste_disposal though only operator is configured.
