One of the things that I find difficult is in the Build menu, you can't sort or determine what you have built and what you haven't. On some of the blueprints it does say that you have built something, but you have to click on it. It would be great if this was colorized in some way. Also, in the case of benches, it would be great to be able to obsolete benches that are no longer needed or at least hide them from view.
