Added the ability to manage nested content items without needing to navigate away from the current content item.
You now have the ability to create new content in-line when building out a content item. This item can be marked as embeddible
or referenceable
. Embedded content items are only visible to the current parent item and share the same sandbox life-cycle as the parent. Referenceable items can still be created / updated in-line but have their own sandboxing life-cycle. These can also be reused by other content.
