On the "Your settlement has grown a level" popup, I cannot tell what that city produces, nor can I tell what I chose to specialize in on the last level up.
1) Allow the user to see what that city currently produces ie 5 Materials per turn, 1.8 Gold per turn etc
So that I can determine what exactly I want to specialize this city in
2) Show me what I chose during the previous level ups. So I can tell if I want to further specialize this city into one resource or generalize the bonuses into different areas.
If the user has 30 cities he/she cannot be expected to remember this information to best determine how to level up a city.
** Does this bonus actually accumulate with each level up or does it replace altogether the previous bonus I selected. I currently have no way of knowing this as a user.
