Thanks much. I ended up subclassing an NSView to draw the required things, subclassed another view to be the containing superview and hold controls, and override in the containing view the addSubview method to always have it call super and also add the drawing view-subclass at the end. That way the view is always added on top of all others. In the given scenario the containing superview dynamically loads subviews anyway, so overriding addSubview seems to be the easiest path.
