This is great, however the UI presentation of buildings needs to be completely reorganized In identifiable categories (like, happyness,military, growth, development...). it's too cluttered in those preview screenshots. Maybe add a toggable screen like EU4 ?
yes please, the current UI is awful. Looks like an amateur indie game. A displayable window like in EU4 or something would be way better. One click and you can get a big screen of all the buildings, clearly see how many you have and see each type, and their effects.
If you dont want to go through all that, you can always use the macrobuilder.
