UPDATE: This is implemented for the contacts app. All other content apps should be adapted accordingly.

Most implementations of WorkbenchSubAppView are simple implementations that add no logic of their own. It would make the content app classes even easier to use if adding your own such implementation was optional.

See for instance:

• info.magnolia.ui.app.security.view.UsersViewImpl
• info.magnolia.ui.app.pages.main.PagesMainViewImpl
• info.magnolia.ui.app.contacts.item.ContactsItemViewImpl
• info.magnolia.ui.app.contacts.ContactsViewImpl
• info.magnolia.ui.app.security.view.GroupsViewImpl
