like visual edits to ui?

Yes, more or less. I've been tinkering with what this might look like this summer, but haven't found a good solution. Seeing your "exploded view" of the backend resonated on that front.

But instead of the nodes representing steps in a workflow, you'd have screens/views as nodes. Now, how the user would handle layout and components at that level, I'm not sure, but that's directionally what I'm asking about.

I hope that makes (a little bit of) sense.
