Apologies for lack of clarity, I agree that a square board for chess is probably what we all need, and it does fit onto my screen nicely. What doesn't fit on my screen is the useful information that comes down below the level of the board. i.e. game details & notes, time control data. Then there are all the various menu options at the top of the window. These all take up scarce inches top to bottom on my screen. However, being landscape shaped, my laptop screen has lots of unused empty space at the sides. I feel sure that some of the information above and below the chess board could be moved to the sides.
The Analysis board is perhaps less of an issue, but that still comes up in a Square Window and on my small laptop I have to scroll to see some of the useful information below the board.
Don't get me wrong, this is a great chess site, I was just hoping that suggestions from those of us who use it might help make it even better in the future.
