Saw it today on Twitter. Love at first sight. Really great. I will try it in production for a small project soon. Curious to see if it's useful beyond tutorial/learning/simple bootstrapping use cases. (Also really nice that it's not strictly bound to cilium but integrates well with it. Makes it universally useful).
Biggest issues so far: Can't edit yaml without export/re-import. No offline use (i.e. it could be gone anytime, my boss doesn't like that).
