Yeah, I really like the idea. One my long term goals in my editor is to have something like this. Focused a bit more asynchronously. But I love the focus on the code as the grounds for the conversation. It is so hard to do that today with so few tools to help.
Have you seen this
on using tests to find interesting subsets of the system? Seems quite a bit in line with what you are doing.
I've got to ask, was the direction of inspiration here truly from the episode to the tool? If that's awesome. If not, nice tie in 🙂
