The add-on sort of works but is unreliable and doesn't place pins on your board of choice, you'll have to go into afterwards and sort into the correct boards but this is just another annoying feature which came when they completely redesigned the previously excellent Pinterest front page where boards were easily displayed. I lost a mass of perfectly organised pins when I moved from one side of the world to the other and stopped using, thought I'd give it another try but its still pretty abysmal.
