Tiny eco-UI suggestion

It would be cool if we could see how much metal and energy a whole group of fabbers uses. As in, when you select the group of fabbers which are building something, you see the group-info-box and it also shows you how much metal/energy this bunch uses in total. The same could be done with factories and such! So we could even try and select the whole base to see how much ressources are used in total. ... Or we simply get a "How much metal do you we use" info box next to the metal bar like in supcom.
