Fancy large galaxy map

**What do you want to see?**
A fancy large (perhaps almost fullscreen) version of the galaxy map that can be brought up. It can show a lot more details about star systems than the regular tiny galaxy map.

**How would it help players?**
Better planning of strategy

**Alternatives**
???

**Screenshots and mockups**

**Things to consider**
What exactly can this galaxy map do that the regular map can't? Space Empires 5 could provide inspiration, perhaps also the strategic mode in Gratuitous Space Battles, or MOO3/4.
