bear with me since this issue has plagued every single OS I have ever used.
Back in the days of XP it was fairly easy to disable the services you had not the need for since the list was fairly minimal. In 7/8 it is an exercise in torture but it remains possible.
I attempted to do this in the 13.04 dev install, I was sucessful but it was quite complex since I had to use sysrv something in the terminal and then another for upstart etc...
I'm posting this because I saw a beautiful example of a services control panel in a small and unknown debian based italian distro, they make it so easy to disable stuff like cups etc that I had to show it:
I would suggest having the ability to disable not only stuff like cups/bluetooth but also video photo scopes and indicator-keyboard-service and printer-service etc... (pretty much all the bloat like scopes and indicators and non essential stuff). If you could integrate that in the 'System monitor' app it would be terrific
