What private methods are you overriding? I'm curious to know for 
compatibility  reasons. And beware that your app may break if you 
override private methods.

I would be vary careful when you introduce generic names like this in 
a subclass of an AppKit class, especially if it is likely that AppKit 
may introduce a method with the same name at a later date. What if 
AppKit adds a "hidden/setHidden" property on NSTableColumn? I can 
cause compatibility problems, since the framework may start 
accidentally calling your method. This is just something to be aware of.
