Thanks!  I did try to follow the Marble/KDE/Qt style guide... :-)

I've just checked: everything is good.  Thank you for applying my
contributions.

* Actual handling of the GeoJSON Simplestyle icon styles would be
  nice, extended possibly to be generic for all formats: location
  pins inspired by Google Maps, Mapbox and Leaflet.js [1] where you
  can select a pin, a colour and size for the pin and an icon (say
  from the Maki icon set [2]) to be inside the pin.

* Editing and saving of GeoJSON files within Marble to be on par
  with KML?

My greatest limitation is available time!

Yours truly,

John Zaitseff
