Just because Snapchat mostly revolves around disappearing messages doesn't mean you always want those snaps to go away. In fact the company wants to help you do just the opposite -- it's launching Memories, a feature that saves both snaps and Stories for posterity. Once you've saved shots to Memories, you can create a Story from them or even link multiple Stories together. If you've been using Snapchat to document an epic vacation, you can share the whole thing as a giant collection of photos and videos. You should see the feature arrive sometime in the next month, and you'll get a chat when it's ready for you to use.
