Systems administrators: Administer Linux with Trinity desktop tools

I found the following article interesting:

http://www.ibm.com/developerworks/linux/library/l-admin-gnome/index.html?ca=...

Trinity does most of this. I was thinking we could write a similar article for our community wiki.

Questions:

* How to set default file manager (konqueror) viewing preferences for all users? (Figure 4). The author did not imply setting such default options globally for all users was possible in GNOME, I'm just asking whether that is possible in Trinity.

* Does Trinity provide a GUI tool to manage system services (not Trinity services)?
