[development] How to move taxonomy fields from the categories fieldset?

[Angela Byron]

I found an old thread where this was asked about but it didn't seem  
to have a resolution: http://lists.drupal.org/archives/development/ 
2006-03/msg00511.html

Basically, I'd like the ability to take the stuff in the "categories"  
fieldset (specifically, free-tagging vocabs, but any and all is  
good), assign it some arbitrarily weight, and place it elsewhere in  
the form.

Anyone have any pearls of wisdom? I hereby volunteer to write up a  
nice little tutorial about it for the handbook if someone can throw  
me some sample code.

Thanks a lot,
-Angie
