i knew that one slick, but roanons ideas are very nice and useful, thanx a lot
another thing I use to min/max my empire: I click on the production thing, and then on usage. this way I can check which planets of mine are using very few minerals (lets say something less than 1500 per turn) I check them and try to change my designs, buildings ques or what so ever in a way to maximize this. not useful at everytime, but a nice way to ensure that your empire is constructing at its maximum lvl.
