On the main galaxy map I would like some icon to show you planets that have a starport and another to show you a planet who's starport is building something.
Also I would like industrial development rings a la moo3, where we can tell by looking on the planet on galaxy map two things: 1) How build up it i s in terms of current structures vs max structures. 2) How many structures are queued/finished out of maximum structures. This would make surveying your empire a total breeze! Just look around and you can tell where your weak points are that need fine tunneing. No more boring clicking next in colony screen (I hate that).
