I am not sure if I am the only one but what about a coordinate system where let say one finds a planet or wormhole and want to know where to locate it after exploring this system.This was be a sort of ease of life implementation.
Note: This idea could be implimented in a later build like when the squadrant feature is initiated.
Edit: Here an example.
You found a wormhole and it is located at X:__ ,Y: ___. The X and Y coordinate would be noted on a piece of paper and maybe in the future there would exist a menu where all saved coordinates can be accessed.
