With the new ProgiParts for shop workflow and the tabs in the navigation bar (ressource_pack 6.1), Annie suggested to place a new tab for Credits.
The sub tabs could then be To be credited, Credited and Refused. Each sub tab could then get the very own set of notifications, for instance To be credited and credited shall not and Refused yes to get the user attention on the credits that really matters.
Annie thinks Credits is department on it's own and should be made more visible.
