I find it confusing that if you have a build/training window open, and the select a different city by clicking in it or on it's square icon, that the build/training dialog does not show the options for the newly selected city, but rather for the city that was previously selected. It would be nice if the build/trainiing options changed to reflect the currently selected city, or at the very least closed the build/training dialog when a new city is selected.
