Right now you walk about the map of the small spacestations, and on the main ones you get a menu. Obviously this is inconsistent and the main reason for it is feature creep over the years.
Some people seem to think the main stations should be maps too. I think the menus are much more practical.
Of course a third way to handle this would be this:
On the first visit you get the map. Second visit you get the menu (If you haven't found a particular shop on the map it would obviously be missing from the menu), and there would be an additional point in the menu "Explore site" that takes you to the map. The pirate planet and other locations could behave like this too (The black market and the independent colony for instance)
What say you, fellow prospectors?
