hi all After spending a couple of hours redoing I imagine the same process as Gary and reading all the code I can tell you that people wanting Etoy to load back in any squeak versions do not know what they were talking about. seriously! I'm amazed by the amount of abstractions that could have been put elsewhere. Now if we try to learn from that here is my take on it: I think that what was missing is a kind of layering system so that etoy developers could enhance Morph (since I imagine that they wanted that any objects in the system could be scriptable, react as a card.....) but layer it and remove cleanly. May be a kind of classboxes system is what they should have implemented so that when you were in etoy you could get all the stuff but when when you are out of the etoy project you would get a nice little morphic.
