That looks nice, for really simple things. I wonder though, how people really use stuff like this and what are the key things that make them find it useful? I've tried different approaches and found flowcharts mostly only work for really trivial things, and even then only if there's a very strict hierarchy (which almost nothing actually is). Get into even a single module of code (never mind the whole system) and a chart at any significant level of detail becomes an illegible mess. At best just an image to gloss over in a slideshow to try to look impressive, without actually trying to explain anything. Anything with any complexity needs a wikiweb of details and relations. And that's a mess to maintain. But I do love the idea. And making it simple and easy to do with the keyboard is great. Just wonder how people actually use it.
