The global settings of the plug-in can be edited in the navigation menu under Settings. Please note that only administrators can edit the settings.
In the current version, only the general settings of the interactive map can be made here. The position of the viewport (latitude, longitude) and the zoom level. The appropriate coordinates can be found with different maps such as Open Street Map.
The settings page is at an early stage, but provides a solid foundation for the addition of further settings options.
