Auto potion drinking please... would be nice to make a load of potions, then set them to be used when the old ones run out. Being able to set this for each worker to drink a different potion would be really helpful.
Thanks for the upgrade window... it's a step in the right direction, but a couple of suggestions:
1) Show the current price on each button. You will need to cut down on the text, but "Mining Power" could just become "Power" as there is a mining symbol at the top and so on...
2) Make it so that the prices change when you hold a key to buy multiples. Holding ctrl to buy 10 would be very helpful to know what it will cost!
