I've got a cool idea about a new feature that could be implemented in SpaceEngine.
In Star Trek they use Sectors to navigate in space (or at least to tell which System is in a specific location/ region of space).
A guy created a
Guide for Sector Classification. Maybe it would be possible to implement such a system also in SpaceEngine.
For example: The milky way is divided in 4 quadrants, each has a subquadrant and so on. The outcome would be, that a Sector Block would at most has only a few solar system in it. So the determination and coordination would be very convenient.
