Besides my other comment ; I like this idea and I have been thinking a lot about code understanding and overviews. As I get older I notice my memory degrading and I read a lot of codebases for my work, hobbies etc; many are very over architected and pretty annoying to grok. How can you rapidly understand where a specific functionality is? Etc. Codebases that have been thought out, nicely organised etc are a joy, but many, especially, newer ones I see, take going across 10+ files (in 5 packages) (with a number of build steps) to add/change a simple thing. And IDE's are not helping with that at all.

Luckily I usually find the patterns used and know the tools and libraries used, but indeed some things make me sigh deeply as I know i'm in for a dig in a pit of the damned when having to diagnose + fix something.
