Something included with the Lumia Black update available for Lumia devices on AT&T is the App Folder. Sadly, Lumia Black isn’t available on Verizon phones – however, the App Folder application is. I’ve been wanting app grouping on my Windows Phone similar to Windows 8’s app grouping since I got it. That’s unlikely to happen. However, having folders for my apps allows me to keep all of the apps I use on a daily basis on my Start Screen while reducing clutter. You can create folders within the app and pin those folders to the Start Screen. It does have some cons as it’s not as fast as just launching the app from the Start Screen, but the benefit of keeping things in order is certainly worth the minor inconvenience.
