Personally, I like the way the map looks better with Starscape on, but I agree with everyone else who's commented that it'd be much more useful if it also displayed detected hyperspace slipstreams.
On a similar line of thinking: make the fuel range indicators less "cover everything" and have them on by default.
The majority of the time something along the lines of a small orange ring around in-range stars would be plenty.
To be perfectly honest, I don't see much of a point in the fuel range overlay; if my destination is one of my colonies or in the core then I can probably get 'enough' fuel there if I need it, and I don't find heading out into the fringe to visit just one system a particularly worthwhile use of my time even for a bounty of one form or another. Furthermore, between hyperstorms, slipstreams, and the occasional hostile fleet I don't want to fight, I find that long trips through hyperspace rarely follow the ideal straight-line path at normal fuel consumption that the fuel range overlay appears to assume.
About the only thing that the fuel overlay's good for is quickly checking if I have more than enough to get back to a place where I can reliably get more, but between fuel not competing for space with other cargo and in my experience generally being fairly cheap I don't see much reason not to carry plenty of it, especially if I'm planning to leave the core, and anyways I usually find fleet endurance to be more limited in practice by supplies than by fuel.
