==== Create System Icons on the (KDE) Plasma Desktop ====
----
I like to have the system icons, like trash, my computer, home and network on the desktop.
There's no system configuration that simply switches them on - I guess the developers have another taste ..
But, it's easy to do: just create a simple text file for  each in $home\Desktop 

=== Home ===
Create ''$home\Desktop\home.desktop'' and add the content:
<code ini>
[Desktop Entry]
URL=$HOME
GenericName=Home Folder
Icon=user-home
Name=Home
Type=Link
</code>

=== My Computer ===
Create ''$home\Desktop\computer.desktop'' and add the content:
<code ini>
[Desktop Entry]
Name=My Computer
Comment=All system files
Icon=computer
Type=Link
URL=/
OnlyShowIn=KDE
</code>

=== Network ===
Create ''$home\Desktop\network.desktop'' and add the content:
<code ini>
[Desktop Entry]
Name=network
Comment=Network shares
Icon=preferences-system-network-sharing
OnlyShowIn=KDE
Type=Link
URL=remote:/
</code>

Create ''$home\Desktop\trash.desktop'' and add the content:
<code ini>
[Desktop Entry]
Name=Trash
Comment=Contains removed files
Icon=user-trash-full
EmptyIcon=user-trash
Type=Link
URL=trash:/
OnlyShowIn=KDE;
</code>
