Yes, that’s right. As far as I know it’ll probably be available by the end of the year?! Having a download button on Netflix is about 10 years to late
But I don’t think you are able to save the movies and shows on your hard disk, because you’ll only be able to watch them offline on their plattform for a certain period of time. Therefore you’ll need a third party software like a screen recorder. This one does a good job:
