I am not suggesting this. It is just a thought.
I realize that doing the following requires one big instance and that might not be possible but...
...just for fun...would it be cool if there were no "normal space", but everything took place in supercruise mode. All travel and combat, as well as all signal sources and all other things present in the system were present and you could slow all the way down to zero and stop right at the nav beacon, as an example.
Then, there would be things to fly around during combat. Such as combat around the sun or a moon or with whole systems whizzing by. And we would have full thruster control over the ship while supercruising.
