i might be misunderstanding, but Altair and Sirius are two separate sectors in the same galaxy, separated by hundreds, if not thousands of light years from each other, each with their own body of planets and stars. Separating them into Altair, Sirius (and if you want) the Inner Core helps with filtering through systems to help someone find their way out or assist in plotting a course.Unless you want a super category like "All Systems" and break it down by sector>house>system all on the same list…
