Very interesting concept, thanks for sharing! Context and intent are critical when trying to understand code - this looks like a useful way to capture that. Merging the call stack display with the "debugger" is IMHO a particularly good idea.
Out of curiosity: have you explored stories for code _over time_ at all? It might be useful to be able to build stories for a block of code that change from commit to commit as the code itself is mutated.
Yeah watching a section of code over time was what I thought this was going to be initially. That sounds really useful for sharing the story of "how we got here" to new devs.
Yes - easily able to do a diff with previous versions will be of great value when creating a story. Its in the feature list backlog. Will get on it soon.
