If I want to change the name of the NSOutlineView column to which the #define statement referrs at some time in the future, I'll have to change both, and likely forget one. Is there any way around this without placing the #define in my NSDocument subclass's .h file?

You could define a constant method (like in SmallTalk) in your main class, that your categories can call e.g.:

- (NSString *) sourceListColumnID {
	return @"sourceListColumn";
}

This can be called from your categories and you won't have to duplicate your constants

Thanks again!
