OK, I have to say: it’s still not ideal. You can still have compiled methods that I don’t know how to introspect with prettified code like in the System Browser. You can still mess up too hard with the UI itself without any undo option. And on top of that, you lose the ability to save morphs into files (unless I’m missing something)…
But it feels like it’s the closest any environment has been from being truly user-programmable imho. I’m actually not struggling too much to understand it, just asking it to show me how it works, and copying stuff around to make it my own.
I feel like giving this one a 7/10.
