NavMarkers and Skylark Belt

Top down, in game view of part of the Sol system with both enabled.
NavMarkers is included in the server modpack.
Skylark Belt is a plugin that must be loaded via Pulsar Plugin Loader.
Both together can show you the borders of the Nexus sectors, mainly to avoid dipping into them on your route elsewhere. Some additional setup is required, but once done, navigating the Sol System Map becomes even easier.

:NavMarkers:creates a folder if you have the 'GPS Folders' plugin and is ignored if you don't.
Go to 'control' tab, any 'cockpit'. Look for the 'available GPS' list and add all those markers to the list below that one
Colors roughly match those from the System Map.
Excluded from this list: Sol, The Belt. Both sit on 0,0,0 anyway and NavMarkers can't show us anything useful. Do !nexus sectors true to get those if you need to.
You can hide the spheres at any time via 'control panel' -> 'cockpit' or by putting a cockpit with the 'toggle navmarker' action on any hotbar.
Create your own markers by adding (R-XXX) or [R-XXX] to a GPS name. XXX is the sphere's radius in km.
Color of the spheres is based on GPS color at time of creation.
