SUMMARY Plasma 5.18 and above has hidden toggle to "lock widgets". To enable this mode, run the following command: $ qdbus org.kde.plasmashell /PlasmaShell evaluateScript 'lockCorona(true)' After running this command, all options like "Add Widgets..." or "Add Panel..." will be hidden in the right-click context menu. However, Latte Dock will still have options to edit and modify the dock. STEPS TO REPRODUCE 1. Run the qdbus org.kde.plasmashell /PlasmaShell evaluateScript 'lockCorona(true)' command from terminal. 2. 3. OBSERVED RESULT Right click on the Latte Dock shows "Add Widgets...", "Add Dock/Panel", "Edit Dock..." menu options. EXPECTED RESULT The "Add Widgets...", "Add Dock/Panel", "Edit Dock..." menu options should be hidden.
