Do not use. Opening the editor will convert your config to the new format and possibly break it. Probably full of bugs.
TODO:
- Only upgrade deprecated configs once, probably by checking custom actions field type.
- Strip leading and trailing spaces from upgraded styles, leading whitespace seem to break them.
- Stricter autofill logic and possible key/source/keyboard ID removal logic. As it is now it autofills with entity ID and doesn't get a chance to autofill with a different ID.
- Stricter update element config logic, possibly only run on default actions.
