 - Unfortunately, I had to remove KML support for now, Maplibre is not displaying the custom graphics one can put in KML files.

 - Map controls are limited when in follow mode, zoom, rotate, align to North will only work for 0.2s and then suddenly stops. This is due to how the plane icon is refreshed, which is a blocking operation for the map.

+- Xbox support is not possible due to the lack of SimConnect SDK in the Xbox release
