Game board disappears too fast when someone wins on AI single player.
I'd like to look at what happened a bit longer.
You can. After the game is over, and you have your avatar plastered on the screen because you kicked ass, click on the statistics icon. Then if you want to see the board as it was before you won, click on the checkmark. It'll take you back to the final board layout before the win.
Why even throw the win screen at the players? A small window is enough. The UI developers are so obsessed with each new window completely blocking out everything else on the screen. Please see "non-modal" windows and try to use them (especially good for trade but you could use it everywhere).
