Desktop Switching Tool

[JD]

The Desktop Switcher:
System -> Control Center

opens up the gui app for all kinds of system settings.

One of them, in the System group, is called Desktop Switching Tool.

When selecting this tool, it displays the names of several DT's:
Gnome
KDE
TWM
FVWM
ICEWM
System Defaults

But no selection available for Mate.

Is this something that the Mate devs should address, or some other group?
