Completely disable desktop Notes (KDE Plasma 5)

I'm running Fedora24/KDE5. Every time I accidentally middle click the desktop or drag a file/tab from a text editor onto it I get a "Note" stuck on the desktop.

I can remove it by right clicking the bottom part and choosing "Remove Note". I can disable the middle mouse action in desktop settings (from right click menu). I can't stop them appearing when dragging files (just noticed when dragging a tab from my text editor). I want them completely gone. Is there a package I can uninstall or some option to turn them off?

• Right-click on the desktop
• 'Configure Desktop'
• 'Mouse Actions'
• To the right of the button that says 'Middle-Button' there's a button that says 'Paste' and then some more buttons.
• Click on the rightmost button that looks like a minus sign,
• then click on 'OK' or 'Apply'.

You can remove individual notes by right clicking on the (almost invisible) border around the note and selecting "remove this note"
