Space Privacy - Extranet for Confluence

We regularly see that some of the Space admins use the standard Space permissions for permissions instead of just the extranet user administration - which can lead to undesirable side effects. Therefore it would be helpful if a corresponding note (possibly with a link to the app documentation) could be added to the Standard Space Permission dialog in Space Privacy Spaces.

If I assign a user to an extranet space, I want to see more information, e.g. their email address, because names may not be unique, and there's the chance that the wrong user is assigned.

As a company that uses Confluence Data Center I want to be able to use an approved Confluence App for Space Privacy that is fully compatible.

Internal users should be able to see all other users in the system, no matter if they are assigned to an extranet space or not.

As a user, I want to know who is an extranet administrator in my extranet space, so I know who can be contacted in case of any questions.

As an administrator, I want to be able to check which users are visible for another extranet user (visible in their people directory).
