labels could be more descriptive

[missinglink]

some of the labels could be more descriptive, eg: Madrid should be Madrid, Spain

    {
      "type": "Feature",
      "properties": {
        "id": "3387:adm1:es:esp:madrid",
        "layer": "region",
        "source": "qs",
        "name": "Madrid",
        "country_a": "ESP",
        "country": "Spain",
        "region": "Madrid",
        "label": "Madrid"
      },
      "geometry": {
        "type": "Point",
        "coordinates": [
          -3.71701518231323,
          40.4950680111115
        ]
      }
    },
