I pushed your code to GitHub, with a small change: In Cuis we generally 
prefer to ask #is: and not #isKindOf: . It is generally faster, but also 
gives the object the opportunity to define itself if to be included in 
some protocol / category / grouping of objects, instead of using a 
rigid, system enforced criterion.

Yes. That is a good idea. I guess that Object could answer #() to 
something like #inspectorMenuOptions, and each class could add its own. 
This should be used both for inspectors and explorers, and integrated in 
#fieldListMenu , including what currently is at 
#addItemsFromDictionaries: , #suggestObjectSpecificMenuItemsFor: , etc.
