Just a quick one today. A client needed to allow a group of users to add navigation links to the Quick Launch on their SharePoint Online sites: We mistakenly assumed that granting the Design permission level would be sufficient. That's not the case on SharePoint Online when the Publishing Infrastructure site collection feature is enabled. The EDIT LINKS link doesn't show up until you grant the Manage Hierarchy permission level. Alternatively, if you want to get granular, you need the Manage Web Site site permission.
