Featured Articles PRO comes with user permission implemented by default. When installing a fresh copy of Featured Articles on your WordPress powered website, you, as administrator (and any other administrators), will have full access to all plugin pages.
Additional user roles (editor, author, contributor, etc) can be allowed to manage Featured Articles sliders from plugin Settings page. Allowed permissions include management of sliders (create/edit/delete sliders), slides (create/edit/delete slides) and slide groups. You can selectively choose for each user group the actions that they can take.
