The large # of flags quickly became a problem (see
https://www.kinook.com/Forum/showthread.php?t=5825), so I have made a few changes:
1) Ctrl+Shift+M flag menu will be limited to 12 flags
2) The Item | Flag menu (and keyboard shortcuts) will be limited to 20 flags
3) The default # of flags created in the Flags dialog will be 20
You can still create additional flags if needed, see above.
