I think it would also help to have the factory list to have various colors.

Example: if have the right tech and you have the right amount of resources - then it is listed as yellow (player knows he or she can build it).

If missing just the tech a different color. The resource example is more important but any little indicators would help when flipping through the empire. I think as the factory list grows during the game - this would help a lot.

Right now an item is in white and I click on it only to learn do not have the right number of resources.
