I'm half way to finish the retouching of galaxy. It is a structure and cosmetic change that improves alot the beauty of the game and, my 5 c opinion, creates a more realistic galaxy.
This idea was somehow put in the vanilla game but just partially, it seems like the creators after preparing all that good stuff, got hurried just at the final stage of tehir work: the galaxy layot
The general idea is this. As axample. Argon Prime is the main abitable planet of the system. I assumed that every system has 1 abitable planet, well I know, binary planets, terraformed planet (Mars could be terraformed). So some exception is there. Then from Argon Prime you can fly to its moons (inabitaded). Essentially the system spams on 2-3 sectors (in SCI-FI usually 'sector' is used to delimitate vast part of a galaxy including several systems, but it's not the case of X3)
So, if you want to jump to other systems, you must first fly to one of the moons. Moons are the "transfer point" of the system. Sectors are no more all connected in a "random" way, they are groupped into systems connected through the "transfer points"
So teh actual layout looks like this

Cosmetically, the sectors belonging to the same system share the same background and sun, of course. Then, assuming the galaxy map being a part of a spiral galaxy, the background change accordingly: the southern sectors are remoter and the northern are nearer to the core of the galaxy, so the more you go "north" the bigger the white galaxy core appear on backgroound. Then, when you go into nebulae, sometime first you find yourself in the border, so still can see stars, then going inside the nebula is bigger and brighter. There is a map I'm inspired by, I already put it in thi post, I think..
After galaxy completed, the next step is to eliminate jumpgates between main planet and moons (or neighbour inabitable planet, as e.g. Earth-Mars) and just leave the gates connecting the many transfer points (e.g. Earth Moon <-> Io or Europa; Earth Moon <-> some Proxima Centauri inabitable planet's Moon). Then from moons one can treavel to the planets, but not directly jump there.
Unfortunally you can not simply eliminate jumpgates, and use a script to tranfer you, becouse this wai AI ships would be unable to jump away.
Also for this I need the help of Cycrow, who is working at a script that work also with NP ships, for its Star trek mod.
So, I foresee a release very soon but without this enhancement that requires some scripting, for now only a better layout and cosmetic, and the idea of transfer point partially put in place
