Okay I spent all day trying to tweak a new production menu out of defragens design and I couldn't. The main issue is his design is it is designed to make selecting units faster. However because not all the units can fit in a 3x3 you would need something like a 3x6 which is huge. I made a 3x6 and it was simply too large. So if you used the 3x3 you'd need scrolling and that defeats the purpose. Also it is important that the original design is available by default and his design does not transition well.
So I thought about it and we really don't need a fast selection, the mouse scroll is pretty sufficient. What we do need is the ability to quickly set to your "preferred default" and the ability to set a building queue. Mainly a queue is needed so that you can do something like tell your fort to build a crane without canceling something or changing the build cycle (just stick one crane in the queue and let it end and repeat with what it was already building). Or maybe that jeep is 90% and you'd rather tell the factory to start cycling heavies after the jeep instead of canceling it.
So after 8 hours of hell because I am not a graphics designer I give, whoever you are or aren't, this -http://zod.sourceforge.net/screenshots/production_expanded_test.png
