Raimo,

I get what you are saying; thanks for the enlightenment. Still, I think if I
had a list of available data points (and you could create the
process_info_items() call only to return the interesting ones, possibly), I
could display them to the user, who could decide, no, that one is ugly and I
won't select it for display. Isn't it better to give a choice and have
someone refuse it, that to deny it to them? I don't know. It's just a
thought.
