Let there be two page templates who's areas have the same name but allow for different components.

As a content editor I want to be able to clean up my page content after changing it's template. To achieve this I want all contents, that are no longer allowed as area content

• be rendered but not editable (already done )
• be marked as invalid somehow (empty edit bar with message, red border....)
• be deletable - delete action must be available ( )
• their template changeable - template change action should be available ( )

Current status is a real problem for areas of type "single", like stages. They cannot be edited any more when the old component is not allowed in the area of the new template.

The workaround of using the JCR editor is not suitable for all editors.
