I am trying to use the new functionality introduced in the 2.2.0E version as documented on the Wiki.
However, logged in as Content Manager, I just can't find the additional action in the UI to create a layered directory in a staging sandbox. Is it already surfaced to the Web Client or ready for use but not through the UI?
You'll find the action available to Content Managers and Admin users in the Staging repository. Because it sets context for all user stores (as they are layered atop Staging), this is one action is exposed directly in the read-only Staging store.
