I fully agree (on the visual editor)! It's a great property of Cycle.js apps that there is a one-to-one trivial map (isomorphism to be more precise) between the program source code and a data flow graph, so I wish I had time and resources (or hope someone eventually does) to build a tool where you can work in both code or data flow graph. I'm interested in the data flow graph as a "minimap" (think Sublime Text), not as a replacement to actual code (I dont think we can get rid of code just yet).
