Compact mode

[ghost]

Okay, I tried a compact mode feature. If you don't like it, feel free to tell me so, this is a branch.

I just couldn't put the compact window in the center of the screen, but other than that it works fine.

Hi, thanks for your help, but for "compact mode" I imagined a responsive layout (when the window has height>width) where information don't get hidden but are visible under the chessboard (in a more compact mode).

Okay. Fair enough. I couldn't solve some problems already. I'll wait for your version. Thanks.
