If you want to disable certain includes for non admin users, simply go to Featurstile > Includes > edit Include > Hinzufügen verboten.
For example you make want to prevent users from using the simple-content downloads include. For this example you would go to Featurstile >SimpleContentController edit Includes > INC_SimpleContent_download edit > Hinzufügen verboten.
Note: in the example above admin users will still have access to the download include in the dropdown, only if you log in as a non admin user will it no longer appear.
