Create Story Playlists
Sometimes visiting the Story page to check what your friends have been up to is exhausting. Watching all of your friends' stories on a Saturday afternoon at once would take longer than all three Lord of the Rings extended editions, and wouldn't contain a single hobbit. Although, maybe not? I don't know your friends.
Luckily you can cull down the heap of stories by using Story Playlists -- this lets you pick and choose which friends' Stories to play in a single stream.
Try it out: Tap the circle-shaped thumbnail next to one of your friend's Stories. This turns it into a purple circle with a white checkmark. Now tap any other thumbnails you want added to your playlist, and hit the purple play button when you're ready to watch all of them.
