Bugs aside, yes I think they did. They had a challenge to effectively represent multiple hierarchies to the user in a way that makes logical sense, and still allowing them to get to a particular node (astronomical body) quickly. As a developer, I can tell you that many clever people have wrestled for years with this problem, with mostly limited success. A "treeview" representation is probably the most prevalent, but would not work for Elite. So yes, I'm impressed at how they've done this. Simple. Logical. Looks pretty. Anything that reminds one of the stellar cartography scene in ST: Generations is a winner in my book.
Also, the orrery is fantastic, and genuinely useful. The only change I would make is for the game to remember your zoom / location each time.
Knowing 2+2=4 doesn't make you a mathematician either.

But you're right... it wasn't the OP, it was a few comments down. Sorry OP.
