When you are building units sometimes you run short on resources. When this happens you have two options. Use gold or go to the market and purchase what you need. Can we please have a button so purchase what items are needed? You could show the total price of the resources needed. Press this button it would start construction and purchase whats needed.
This would save users a lot of time. It would also make it so you don't need to remember how many units are needed exactly.
