This applet's purpose is to change the desktop settings for gtk3 panel.
Should work with 17.10 and later.
Applet is essentially a button that launches a menu-like window that turns the desktop icons on and off.
We need to create some files first.
- dbus service file
/usr/share/dbus-1/services/org.mate.panel.applet.DesktopIconsAppletFactory.service
[D-BUS Service]
Name=org.mate.panel.applet.DesktopIconsAppletFactory
Exec=/usr/lib/mate-menu/mate-desktop-icons.py- /usr/share/mate-panel/applets/org.mate.panel.DesktopIconsApplet.mate-panel-applet
[Applet Factory]

- After creating those 3 files just add it to the panel, and tell me how it goes.
