Congrats on the launch. Always wanted something like this to be able to build a more opinionated CMS on top of it for all my projects. My first try was Qards (https://www.qards.io/) but the npm, exhaustingly breaking changes from js libraries + the painful experience I've had dealing with & integrating Netlify CMS into it just left me dry by the time I've actually launched. Was a cool project though and I'm thinking of reviving it one day, maybe with Payload.
