I do feel like it would be helpful to have some kind of reference of which sector each planet is in. In particular I know that when I was investigating people's allies and enemies on my first few runs and trying to keep people straight, it felt not very helpful to be told "Zolot is enemies with Oletko of Chakagola" when I had no idea where Chakagola was or how to get there. Eventually I just made my own list of all the electors along with their sectors and planets.
