...Does anyone know any more about a way to change the map markers in the .icfg file? Or have information about its safety? I've heard elsewhere too that there was a script of some sort people used to import/export markers, does that tool still exist?
I made a tool (for Windows) which is able to edit, remove, export & import the markers. It always generates a backup of your current icfg when saving the new one thus your makers should be safe at any time.
Till now i havent released it but i will in the future.
Here is a Screenshot
