Can you elaborate. I see the structure, in the indenting. My IDE (Visual Studio) has little lines and + boxes that allow me to collapse and expand code like this. It's useless, because the most part I kind of care what "something" is, and the collapse is not replaced with a nice pseudocode "frange the kibbleflits" statement. I have tools that can generate diagrams showing me class hierarchies, call stacks, and so on. I rarely (almost never) find the useful. Maybe you have something different in mind?
