Importing markers in the geojson format.
Currently, only .xlsx (Excel2007), .xls (Excel5), .ods (OpenOffice/LibreOffice), .csv are supported... which is funny since they are not georeferenced formats! :-)
I understand that importation is a Pro feature. For my use case, I can't consider purchasing Leaflet Maps Marker if it does not support importing geojson.
