Drupal 8 has this new configuration management tool at
/admin/config/development/configuration. I have an experimental site running Drupal 8 beta14, and I want to import a few settings into my new beta15 site. I don't want to copy everything, I experimented with various things on the old site and only need a few things on the new one.
What I want to copy are content types, the fields in those content types as well as image styles. But looking at the export tool, it seems I can only export a single item at a time.
Is there a way to export all items of a specific group at once, e.g. all content types or all image styles? And for content types, is there a way to export all the fields as well together with the content type?
