Nice idea, but working erratically. I've seen it collapsing an email header but not the email, not collapsing quotes at all, not collapsing embedded quotes one within the other, etc.
So in a nutshell, it's a mixed bag: sometimes if the conditions are right (? don't ask me which) it will work nicely, but don't expect it to do so consistently.
I rate it 3/5 for encouraging the author into refining this nice idea.
