 // LOREFACTOR: The files in this folder duplicate too much code.
 //             Use mixin multiple inheritance to get around this.
 //
 // LOREFACTOR: Move as much kpMainWindow code as possible into these classes
 //             to reduce the size of kpMainWindow.  But do not split concerns /
 //             "aspects" in kpMainWindow, with half the code there and half here,
 //             as that would be confusing.
