Display 'option/menu item' not displayed when installed on Fedora 28
(I am new to this so I might make an error in reporting. My email address is firstname.lastname@example.org) I recently installed Fedora 28, without a spin. In the hope of adding application and 'document' file links to the desktop, I installed Tweaks (version 3.28.1-1.fc28). When I start Tweaks, the Desktop option/menu item is not available. See the uploaded file. Am I making a mistake, or is there an issue?
