That’s close to what I was suggesting except that I don’t much like the idea of giving a morph a name; it would be more effective to have an instvar in the *owner* and properly track the owned morph that way. For  example in a ButtonMorph I suggest we should have an instvar ‘label’ and when we set the label morph it should be put in that instvar as well as in the submorphs list. That way we can find it quickly, correctly, without the isKindOf: or even isTextMorph. And after all, both of those prevent a graphic label.
