I created some users in our Sitecore 8 instance and gave them the editor roles so they can work in the content editor and media library. I also granted them the rights in the tree in the Security Editor / Access Viewer.
Right now the editors can write into the items I granted them, but they still cannot create, rename, copy or duplicate items in the content editor. In the Security Editor I haven't found columns for these actions.
Am I missing a role?
