My first starmap prog was 3star. It was a cute little 3-d globe that went only to 30 or so LY away from Earth. Vega "Alpha Lyrae" was about as far as it'd go.
Could you include a View Option that highlights the nearest stars up to the chosen distance? Make them asterisked in the map, colour them different, ensure they are labelled, maybe draw some lines on the screen from the point of origin to the nearby stars...
...no need to remove all the other stars, just highlight the close ones...
This would be a big help to all us old Starflight I and SC2 fans
