When there are many roles defined in the portal, the permission settings page is too long and the user needs to scroll.
Scrolling to the bottom the action names in table header goes out of the window and it's quite difficult for the user understand how to associate the role with the righe action.
It's important to have a sticky table header to view always the actions name of each columns.
