minor nit but this feels very much like it was designed by an academic in that I think you could do this in latex very easily but not at all in a standard text editor. Those horizontal and vertical lines. But otherwise you need a specialized program or a whiteboard to pull this off. Also all those math symbols. I don't know where those live in my input.
