This one's been bugging me for a while:
Construction Queue:
There needs to be some way of changing the number of facilities being built in a queue. For example: I set a contruction queue to build 20 Mineral Miners. The next turn, I discover Mineral Scanners. Now I have to go back into the construction queue, remove all the Mineral Miners, add 19 to the queue and then stick my Mineral Scanner down at the end.
There should be little +/- buttons beside each queue entry, so I can just click the minus button to reduce the number of Miners in the queue from 20 to 19, then go and add my Mineral Scanner.
