I think the abyss should remain menacing and impossible to colonize or settle in extensively. I'm not sure how I feel about being able to obtain tens of thousands of supplies and fuel fighting Threat, though it makes sense and is pretty fun.
What I'd like to see is more actual danger. Shroud lights actually chasing you after provocation. Waiting a second and flickering, then jerking towards the player for dramatic effect. Maybe more of an incentive to make use of the normal lights (at present, their buffs are fairly anemic). Maybe threat fleets waiting on top of gravity wells, conducting mining operations and so on, starting out with a small one to let the player know that it can happen.
As for the original suggestion, I've played games where the map doesn't automatically center on you if you aren't near a landmark, and they were fun. Plotting courses with a protractor and so on. It might be a bit of a change at this stage in development, though.
