I am kind of new, I like the request for when you hover over something it tells you a bit about it. I would also like, near the upgrade option on the management tab, it to let you know what the upgrade will do for me. RIght now I am curious as to if I upgrade a transport, does it make it faster? or just add more cargo space, and to the price per turn. this will help me decide if I should just make a second one, or improve my first one.
