Disable/enable 'Restore version' button also on 'permission level'
In permission-level (readers - viewers - owner etc.) you can disable/enable 'deleting versions' and 'viewing versions', but you can't disable restoring versions.
Members who restore a version are not mentioned as 'name xxx restored version7 to version12' but as 'changed document'?? I want them to view but not to restore the versions!
