When I originally mocked-up the interaction I imagined a second, slightly more minimal version (http://codepen.io/kidGodzilla/full/qdLRzb/), & the app generates a "dev blog" from your updates (http://featurekit.featurekit.co).

I also imagined it would be a bit like statuspage.io - You could definitely create it yourself, but would gladly take an off-the-shelf solution if it had good defaults.

I think I could probably keep adding equally-useful widgets if this gets some validation from users.
