Yeah, I've been to one of those already. But that's been a small part of the experience.

Huh? You can't zoom into planets until you are in their systems. I need to know where to go next from outside the system. Jumping to each system to check would be tedious indeed. And… I see no "unexplored" (or "explored") planet labels, even if I am in system.
