Just wanted to put out my two cents. I feel like this game could be enhanced by a small amount of multi display support (which I don't expect to be in the game already due to its alpha ness) 
First thing would be just to have an option to let it run music and everything while in background. This way you can do other things while watching gal civ continue in its grandeur. Another idea would be to allow the game to throw the menus into a different monitor, so you can have your planet build hexes, research, diplomacy etc. on one monitor while the entirety of the starmap is on another, or check out your ship builds while looking through tech.
Anyone else agree?
EDIT: or have a zoomed in starmap with a zoomed out star map, that would also be pretty fly.
