It'd be useful to know that a Content Block is being used by one or more Include Contents, and on which articles.
In particular, if I'm reviewing an article for potential deletion, I might keep it if parts of the content are being used elsewhere in Confluence.
There are two ways in which I can see this being useful:
So we'd have the name of the page followed by a list of the other pages that use the content from the page.
Obviously there are the permissions that would hide from my view the pages I can't normally see, but perhaps there's a way around that by merely stating "Pages you do not have permission to view are using the content in this Content Block on this page."
@Davin Studer made a user macro that does that:
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
