It might be intuitive from the user view point (which is why it had been proposed) but it's a lot of effort to implement & it assumes that 3rd party plug-ins would support it. I'll re-assess this when I'm in a better position to have replaced at least all of the standard preferences & those that come from the included plug-ins (maybe I can do something sneaky like scanning dialog resources or something without overly bloating the code for preferences).
