I mine much less than I try to turn into ships. I get a lot of messages about missing minerals for production, and I can see my non-existant stockpiles and the amount I need to produce all I've ordered. But I'd like to know how much I'm lacking on a per-month basis. Also, how much my mass drivers and ships brought in last month. With the information I have, it's hard to say whether need 50% more Duranium or 500%. Or am I missing something?
