Wes, As you know, I'm all about open source. Education is the key. As long as people understand what preferences do, they can be careful not to change them, or only change them when necessary knowing what the effects will be. You know that the Petaluma, Sacramento and Irvine offices all maintain separate profiles, and they're all open. Yes, that has bitten us once that I remember, but it also allows anyone to fix what may be broken. In this case, understanding the Style command is rather important. For instance, it someone understands how profiles control outputs, but they want to contradict the profile for a particular instance, they can override it in a distinct file (drawing). Education is the key. And then there's always another thing that I support: Rules are made to be broken. But only after you have an understanding as to why the rule was created. If you don't understand a rule (like gravity for instance) be very careful about breaking that rule.
