Good idea, but we dont have to put demo files in separate ZIP. We cound put the demo in same ZIP but in different folder like Document folder with direction on how to install the demo to Assets folder. It is normal behavior of the game. when you press < >, then a city is cycled and selected. If you select any city (via clicking on the city), then Pedia and MainMenu should disappear. This option value go into effect imemdatly when you close the option screen. Main screen need redarw to see the effect. I found redrawing main screen too intrusive and inconsistent with other options that is not related to main screen. Any other option that changes screen behavior should redraw at event of "OptionEnd" event. SHould I redraw main screen, is it better behavior? It is simple one liner. Give your opinion. I have ugly button for it but I fear that every one will laugh at that. So it is not included. But if you wish, I will include it as just "demo". Is there any one who will donate better buttons image for it?
