Thanks for the response. Well, if it's not something to be published or used by others, as long as it suits you, then it works. Personally, I think the addition of denoted inhabited planetary systems has value, however you choose to go about it. My only thought related to your question of "too much." The connecting lines I also liked, though they could be JUST a tad more obvious. But that's just my opinion.

Have you tried this addition without the encompassing chartreuse rings and just the connecting lines?

In any case, known inhabited areas have value IMO.
