I've had this idea in my head to make a notion-like editor which uses Git/GH as it's store of data. When you save, it makes a commit.

Everything is saved as flat json files and image/data blobs.

Seeing this comment, is further solidifying the idea. Notion is a great editor, but having little control over data isn't great.

User should be able to control where the data lives. And when they want it gone, it should be gone. Poof!
