Development: The latest layout definition for the App Launcher makes it easier to decorate.

groups: 
        - personalisation
        - categorisation
        - translation 

this is harder to decorate than

groups: 
        content: content
        marketing: marketing

because of how the information is stored in JCR. It is not possible to use something like this (first approach):

groups: 
        - personalisation
          enabled:false

while with the second approach you can

groups: 
        content: 
          enabled:false

Documentation required - Double-check decoration information and add a note about the reason for the transition to the new layout definition, pages to check:
