A new round:

• Second attempt to restore the systemfont in the mainscreen
• The year digits are removed from the worldclock screen. Conform stock clock and it creates space needed in certain circumstances.
• Removed the menu option to show/hide the background. It gave too much confusion (restart needed) and discussion (correct translation in the menu). I think most just want the background. It is still possible to disable the background as a kind of hidden option, "Background=false" has to be set in "/home/user/.config/worldclock/worldclock.conf".
