Spot on Sir!Both the Galaxy Map, as well as an Orrery System map open up so much potential for the game.
Right now, none of the maps are used anywhere near to their full potential. All manner of data could be portrayed on the galaxy map, along with variety of exploration tools to use. The galaxy map, really could be the starting point for any task within the game...but you are right, it would no doubt require a huge amount of reworking how the map functions. However I can't help but feel the current iterations of all the maps is a massive missed opportunity, they could very easily form the new foundations of the improved game.
