Not really a question, and i'm sure it can be improved, but I wanted to strongly type the output from this awesome editor. Wrote a tiny Value Converter for it. I can share here. Not sure if worth including in your lib. Great work!

[PropertyValueType(typeof(Location))]
[PropertyValueCache(PropertyCacheValue.All, PropertyCacheLevel.Content)]
public class AngularGoogleMapsConverter : IPropertyValueConverter 
{
    public bool IsConverter(PublishedPropertyType propertyType)
    {
        return propertyType.PropertyEditorAlias == "AngularGoogleMaps";
    }

    public object ConvertDataToSource(PublishedPropertyType propertyType, object source, bool preview)
    {
        return ConvertSource(source);
    }

    public object ConvertSourceToObject(PublishedPropertyType propertyType, object source, bool preview)
    {
        return source;
    }

    public object ConvertSourceToXPath(PublishedPropertyType propertyType, object source, bool preview)
    {
        return null;
    }

    private static Location ConvertSource(object source)
    {
        if (source == null)
        {
            return null;
        }

        var sourceString = source.ToString();

        var splitSource = sourceString.Split(',');

        if (!splitSource.Any())
        {
            return new Location();
        }

        try
        {
            var lat = Convert.ToDecimal(splitSource[0]);
            var lng = Convert.ToDecimal(splitSource[1]);
            var zoom = Convert.ToInt32(splitSource[2]);

            var location = new Location { Lat = lat, Long = lng, Zoom = zoom };

            return location;
        }
        catch (Exception ex)
        {
            return new Location();
        }
    }
}

public struct Location
{
    public decimal Lat { get; set; }

    public decimal Long { get; set; }

    public int Zoom { get; set; } 
}


<script>
var map;
function initialize() {
    var mapOptions = {
        zoom: @Model.Location.Zoom,
        center: new google.maps.LatLng(@Model.Location.Lat, @Model.Location.Long)
    };
    map = new google.maps.Map(document.getElementById('map-canvas'),
        mapOptions);
}

google.maps.event.addDomListener(window, 'load', initialize);
