Disable Workspace Switcher Popup
Removes the workspace switcher popup - the overlay that flashes at the bottom of the screen every time you switch workspaces with Super+Page Up/Down or Ctrl+Alt+Left/Right. Works on GNOME Shell 45, 46, 47, 48, 49, 50 and 51. GNOME Shell has no built-in option to turn it off; this extension fills that gap.
