I think that a button that allows you to craft multiple gems at once in the crafting workshop ( in the ancient world) would be super helpful. I have found that I have got 500 raw materials of each type of gem. Crafting each one into the gem above (as going up the gems individually saves so much ancient money) takes far too long. A button that multiplies everything and allows you to craft more than one at a time would be so much easier and faster.
