It is extremely easy to view all notices sent to patrons. But it is not as easy to see system generated emails to libraries. Would it be possible to create a notices tab for libraries, and then wherever we define where internal notices go to, we can select either a patron account (for staff) or a library account (as long as it has an email address defined)? We might still retain the ability to put in a manual address. This would be the exception where we wouldn't be able to track notices, but being able to point to a patron account or library account would allow for easier setup and tracking all around.
Perhaps there should be an Admin notices tab on the admin page so that we could track notices that go to a specified generic address can be tracked as well? That could be an option when setting up emails like KohaAdminEmailAddress rather than inputing a manual address. The email address could be defined on that tab?
