I have two systems, and the right click desktop context menu is different.  On one, it just has:

Konsole
Run Command
Add Widgets...
Add Panel
Activites
Lock Widgets
Lock Screen
Leave
Desktop Settings

On the other:

All of above, except Desktop Settings, plus:
Create New
icons
Paste Clipboard Contents
Undo
Refresh Desktop
Open With Dolphin
Folder View Settings

How do I make them the same?

Thanks!
