[Pharo-project] abouth nautilus and the removal of CodeHolder hierarchy

Hi Ben, i was thinking about the discussion of the menus: Since you are using menu pragma builder, and have explicit views for each tool, then the CodeHolder hierarchy is no longer needed. Because the specialized views get the behavior for answering the actions in the menus (which currently is spread across the StringHolder hierarchy). So this is the main reason why you simple need a pluggable text model, for the model of the views. And a pluggable TextModel (or StringHolder in Pharo) would suffice? Is this correct? Thanks, Fernando
