I think that right click also can be good idea. And I am not talking windows right click type of interface, but the one that gives your icons arond cursor when you right click (those icons can have sub-menues/sub icons as well if you click them).
It is strange that they try to save scrolling time by letting us drag the map, yet they want us to go through the menus on the bottom of the screen, which is fine but if one has "accelerators" through things like double click or middle click or sub-icons through right click that would save mouse movement time significantly.
Also, the more I think the more I like the idea of civilization-like build screen combined with info screen about the city. There is no need to have two different screens if they can be combined.
