RTF is a global modification that replaces all towns in the game.

I would do it like this:

Now I'll explain everything. So: The Elder Council, Magistrate, etc. remains the same.
White - market (warehouse), tavern, forge
Black - fortifications
Blue - foundation
Green - elite
Red - champions
Brown cross - place for the remaining buildings (guild of mages, library, training halls, Tear of Ascha, etc.)
We remove all arrows except for the left and right parts. The building dependencies remain (so that, for example, to build mages, you need a Fortress and a guild of mages, etc.)
Why is this needed? A beginner who doesn't understand the icons will be able to easily see where everything is. (I suggest doing this everywhere, but with different "dependencies"). And in general, in my opinion, this will "bring order" to the cities.
P.S. I'm quite the perfectionist :D
