Request: An additional button to move a thread

Hey, I don't like the idea of deleting threads (although I think the possibility should be there nonetheless). I was wondering if it would be possible for someone to make a mod that added a new button down next to Report, Edit, Delete, Quote etc, that when clicked (and confirmed), would automatically move the entire topic to a 'Trash' forum. Obviously, only the first post of each thread would be able to display the button, and the button should only be visible to admins/moderators.

Any ideas?
