This image shows the System Pages subpage under Pages in space Settings. The label System Pages is highlighted and preceded by a link to the Available Pages subpage. Below this is a Help icon. System pages are listed in a table with four columns: Name, Description, Last Modified, and Actions. The Actions column is divided into two subcolumns, one with a Customize link for each page and one with a Restore Default link for each page. The mouse pointer hovers over a Customize link next to the Activity Stream page, and shows the hint text, "Customize the Activity Stream page using the Oracle Composer."
