A visual editor is definitely on our roadmap. Our strategy is to make the schema easy to read, write and understand. We want to ensure the dev experience of working with the Lowdefy schema is first class so that change review and version control can be as productive as possible.
Adding a visual dev interface is resource intensive can easily distort the schema quality. We figured by first maturing the schema and making sure it works well with dev tooling, we can add a visual dev interface on top as Lowdefy becomes more popular.
