If you want to rearrange a lot of apps at once, it can take a while — unless you know this new trick that Apple included in the most recent version of iOS software, iOS 11. It lets you move multiple apps at once. Here’s how you do it:
Hold down one app until it wiggles.
Move it out of its slot.
Then, with a second finger, tap on any apps you want to add to the stack.
Then, you can move the entire stack to another page or into a folder.
