Actually it's pretty good as is. (Except that it has now beaten me a few times).
I think the the only thing I can think of that doesn't affect the underlying program is the ability to maximize the screen with the top button (just to help my old eyes).

Great work!

PS: There was just one more thing - how about a quick port of Microsoft Office with a button that links to it in case someone want to write a letter or create a spreadsheet while playing Pente? Am I being greedy again?
