I use a flat text file with exactly this structure, just indenting when I need a new layer.

I tried fiddling with it with vim folds but in the end just ended up deleting things I finish.

I learned this from a friend at work.

From a quick glance at the README this supports a slightly more interesting structure than an indented text file: it's actually a DAG where large subgraphs are trees. This allows links between different nodes. That's not possible in an indented text file.
