Bravo!  What's your encore gonna be?
I'm no expert in eclipse plugins.  And actually the editor is a  
little hard to plug from what I understand.  But if there's a way to  
get those !! lines in a lightweight machine readable format, it  
shouldn't be _too_ hard to implement the functionality I was talking  
about.
