nameless clusters make for a terrible map

Navigating a galaxy that is segmented into circles is fun, but it needs a way to address the circles because once something is off the screen in a busy galaxy that's it good luck ever finding it again. Please generate names for the circles and tag objects/items as currently being in those circles.  I play with the maximum possible size and after 200 turns it becomes a very tedious game where you're having to apply all manner of workaround to manage the fleets and jot down all sorts of notes in a pad, and come up with your own conventions of referencing those circles. Madness

Overall though i do enjoy the game. Is there any hope for the AI as well?  yr auto search ships just tend to suicide themselves constantly so i make new ones with big guns on them and they suicide considerably less. is that meant to be the solution?
