Organize source packages similar to JavaDoc ?

Hey all,

I was just busy hacking on a bunch of API and thought how useful it  
would be if my interfaces were sorted away from my classes in a given  
package, instead of all being grouped together. Well, that's what  
javadoc does.

How about sorting classes/interfaces/files in packages the same way  
javadoc does? Interfaces first (in italics), followed by classes,  
followed by exceptions (with enums thrown in there somewhere too). At  
the very end could be any other random files (images, xml, text, etc).

What do you think? Should be a simple matter of replacing the  
comparator in PackageNode.java, right? Except for the italics part...
