I'd actually downvote my own comment right now. There's a thumb that indicates dragability. They're about as hidden as a feature in a menu - that's not great, but it's a lot better than I understood before. (The preview took several hours to download and install on my phone. It's big, but it's not that big that it should've taken that long.)
