to ease VR utilization of navigraph a scratchpad in VR would be amazing to write down taxi and atc clearences.
Im thinking a click function for each section. so you first select your parking space and then the system will automatically know which taxiways are connected to this parking spot, once the taxiway is selected it shall then only give options to click on connected taxiways and/or runways.
similarly with SID/STAR waypoints.
single left click select (mouse default but can be bound to a vr controller if needed)
right click deselect ( also mouse default but can be bound to something else. )
IFR would be the biggest need for sure but VFR version could include nearest VRP or waypoint in a filed vfr flight plan.
