Hi gary here is the vision I would love to have for polymorph. Gary what would be good is that if we could - create adequate hooks in the underlying Morph to make sure that Polymorph can be easily added. - revisite clean change existing morphs that you may have to patch or rewrite to get polymorph The vision is can we have a good foundation on top of which "polymorph" could be build I put "" because it implies that some of the Polymorph changes or widgets may be pushed to the basis and Polymorph may be lighter because of that. This decomposition would make sure that Polymorph can be autonomous from the foundation and that for example you can decline different variants or that other people can define different look if they want. What do you think? I believe that we could get the best of both worlds: pharo infrastructure a better infrastructure and you less code to maintain for polymorph. Stef
