Concentric circles on the galaxy map for ships and colonies

[ekolis]

What do you want to see?
The galaxy map currently shows a circle for each system based on who's there. Change this to two concentric circles - the inner one for colonies, the outer one for ships.

How would it help players?
Now you can see which systems are under threat and where your fleets are in enemy territory! The two don't look identical!

Alternatives
Semicircles instead of concentric circles? A big circle and a little circle in its orbit?

Things to consider
Could the little colony circles be too small on a big map?
