I think it would produce a similar result, and use similar user interaction, as "Extract Superclass" followed by "Replace inheritance with delegation." I want this several times per week, I assumed a request was already in the tracker for it. Ideally this refactoring would allow me to choose instance & static fiields & methods to move to the new class. I could choose to move any static or could-be-static methods which are used by both classes, into a new or existing utility class, as static methods.
