I would like it if you could click the build button and you could see all the buildings you have built and what level they are at and could upgrade them from the build menu.
For example, I click on build and I see 4/4 barracks built. I want to click again and it would expand all 4 barracks in a tray at the bottom of the screen and show a window to my castle on top, so when I select the barrack on the tray it highlights the building on my layout. Then allow me to upgrade from the tray.
I ask for this because I am getting a lot of things on my castle and I have a hard time finding the next cheapest thing to build.
