You are right but first of all, I want to say: Thank you! It looks like fantastical and I like it.
Unfortunately the handling of it is not very workable. After you confirmed the construction you jumped always back to the city overview. Due to my feeling that’s insufficient. I prefer to go after upgrading back to the senat building overview. My second problem is, that I can not change the cities during the time the senat overview is open. It’s very time consuming to leave the overview and changing the city and after this to go back to overview. I would prefer to change the city, during the window is open.
