Hi everyone, I know it’s silly, but having used Windows since the XP days, I’m in the habit of clicking "Refresh" whenever I’m on the desktop. So, I wanted to add the "Refresh" option to the context menu, and I managed to do it by modifying the JSON extension that controls the menu (at line 1226). If you’d like to have it too, I’ve attached my backup files (for Zorin OS 18.1) in the link below.
"Actualiser" is "Refresh" in french !!
