I like the intent of keeping the flow state. Have you considered making this a CLI hook (e.g., a post-commit hook) rather than a web dashboard? I feel like I'd be even more likely to use it if I could just run git commit and have it prompt me in the terminal to confirm the tweet draft.

Funny I had the same idea just now and wanted to validate it to see if anyone was working on it!
