It would be nice to be able to see the current quantity of buildings on a planet when in the build screen.
Two big areas would be farms and terraforming buildings. Since each planet has an optimum number of these buildings it would be helpful to see how many I’m at when in the construction screen. For other structures it still provides information about the incremental change when building. If I have 10 mines then building one more would give me 10% more output.
