When all pages under the App becomes inaccessible (for example, by archiving model), the App also becomes inaccessible and disappears from list of Apps.
There should be some indication to user the App is hidden otherwise:
- User may feel confused for App which suddenly disappeared
- User is not able to create App with same name
Also there should be a method to tell which models are linked to this App otherwise User will need to unarchive the model one by one.
