Important: If you use Jekyll, you do not have to use the draft field, as Front Matter supports the _drafts, _posts folders and collections from Jekyll. If you use Jekyll, make sure to set the frontMatter.framework.id setting to jekyll.
Hexo works also with _posts and _drafts, therefore it would be helpful, if "frontMatter.framework.id": "hexo" is set, no draftField configuration would be needed anymore.
