I just wondered why it was NSTreeControllerTreeNode rather than
NSTreeNode. I'm just naturally wary of solutions beginning "class-dump
shows..."!

Splendid!

I just treat everything at the top level as a group item:

- (BOOL)outlineView:(NSOutlineView *)outlineView isGroupItem:(id)item
{
   return ([outlineView parentForItem:item] == nil);
}

Thank you for your autosaving advice; I did see your code for that on
the list recently, and it will doubtless be very useful.

Best wishes,
