I was thinking on more 360 degrees systems. Most of the Freelancer and Discovery systems are plain sighted. No up, no down. Well I say it would give a more in-depth feeling if you will see systems with upper and down plane space objects, like this : You jump out from another system, near you at 30k you see a planet, another one is located further into the system at 70k above the grid, near it you see other planets/ stars (1-2)/ different nebulaes. When you look down, you see the same (more or less) So the idea is to break the plain sighted view of the normal Freelancer systems. That means variety to give the player a feeling of never ending explorations. My experience from Crossfire and Nightstalker's Universe mod was a very pleasant one because of the variety of systems. And also the size of the stars/planets, it should be refitted. Like, you can't actually see planets bigger then stars.
Another thing I had in mind. I saw you wrote into the wiki about removing from the map of the jump holes. I was thinking of something similar for other space objects, like "exotic" anomalies or phenomena. For instance you enter an unknown system. Your navigational computer it says : Uknown 2 gravimetric anomalies detected, 2 radio anomalies detected, 3 sub-space etc. So mainly your map is empty, you see only the locations of the stars, and your navigational computer gives you a warning with the anomalies that you can explore. When close to them, the distance shouldn't be tagged in K because it would be rather easy to track. It would be good to hide it in Far-Close etc and only after you discover it, would appear in K. But the anomaly should be available only in the uncharted systems ( for instance an Omicron Delta/Iota and even Kappa- like)
And some sort of warning system to aware the player if it entered into a hostile system for him (depending on his reputation) or if its an unknown system (which it will appear the Anomaly Warning system if possible).
