Enable creating and editing a resource in a custom form with option to switch between yaml and form views and keeping them synchronized.
It should be implemented through an extension.
It should provide the entire edit and create page including the header and the description.
Something like this:
{
yamlSettings // if needed
formComponent:

//for translating yaml data to form data
sanitizeToYaml:

//for translating form data to yaml data
// some page based settings for ~new / edit like pages
//form foother settings
handleSubmit, handleCancel?
}
