[Thunar-dev] System icons in desktop

[Linos]

Hello, i have been searching the list and i have found two messages in
xfce mailing list about that but they are from September 2006 so i am
trying now, do i have any way to hide/remove trash,home and filesystem
from desktop icons with icons enabled? i need this feature because i am
going to use xfce in a point of sale system with about 100 desktops, i
am trying to harden the system and i dont like they can open a file
manager too easily, i am found a possible workaround changing thunar
with nautilus but i think it is a horrible solution (i love thunar and
hates nautilus). Anyone can help me please?
