This feature request was created because of the difficultly I had increasing the menu bar, status bar and game result pop-up. My experience was the same as described in https://sourceforge.net/p/pysolfc/discussion/503709/thread/84134ede.
I did not find Options > Fonts documented under https://pysolfc.sourceforge.io/doc/index.html
I experimentally made all Options > Fonts values big but did not see any difference in the PysolFC window (I play only Klondike)
Please consider documenting options generally at https://pysolfc.sourceforge.io/doc/index.html and in the Help available via the PysolFC menu and specifically the fonts with a note about the .Xresources method
