This is a great idea. I'd been planning to create something similar where cells are topologically ordered based on their dependency structure; although I was thinking perhaps to integrate with Jupyter more, eg use their existing kernel web sockets infrastructure. In my mind, one would be able to zoom out and see a graph view where hovering over a node would show its corresponding cell with content / output. Each node might be coloured according to execution status. That said, I'm not a UI expert and I never got around to it. So thanks for your efforts, I'll definitely give it a spin.
