Grey thing. Remind me of these old Amiga computers (Workbench, browsers, late games).
It wasn't like that even in Amiga X-COM. Please fix it.
While I will agree that the GUI is not the most attractive one on the planet... No one is Paying these Fine Men and Women for all this work, now if you'd like to have it fixed and it bugs you THAT much, I am sure they will except Pay-pal
Also for another option, as Psawhn almost pointed out, It is open source so you're welcome to go in and fix it, I'm sure they would welcome the extra Comrade on GUI duty
Also as Eleazar pointed out, The games still tweeking alot of features so why mess with something that works when most of the stuff they have planned or may plan in months to come are not working yet. I myself would enjoy multi-layer bases, but meh, I can't code it so I am just happy they were Kind enough to use their individual and team talents for something Grand and rare such as Sharing a Great concept with NO fees etc. It's rare to find a person, Much less a GROUP of persons that will sit down and make a game with No fee and No thanks... I myself will take whatever these talented individuals make and be thankful they were one of the rare breed.
But again DOOOOO please step up and "politely" help them improve this game
