True, but here's the problem I see:  there is no way to hide or desensitize a 
widget in the current architecture.  The TriggeredSettingsGroup spoofs the 
ability to hide a widget by allowing you to create an empty box (say a 
VerticalSettingsGroup) and raise/lower it w.r.t. the widget you want to hide.  
The Settings class doesn't expose the underlying widget publicly, so there's 
no way to manipulate it.

Apparently there aren't any widgets that fit the nature of this data.  I think 
I'll do the following:  two independent checkboxes; the Help text on the 
"Navigate Buttons" checkbox will have a note to the effect that this option 
is meaningless if "ShowWholeTree" is turned on.
