This is not by chance, the whole framework was built around that design.

And it was thoroughly tested at the design phase, before any implementation, to ensure it would work with all the editors.

There were even some changes to Pydantic itself to support this.

There's a lot of work to do, and for most of it, **YOU** can do it.

The main tasks that you can do right now are:
