Today's iOS home screen limits the number of apps per screen and also the number of apps that can go in a folder. So the user is left to manually organize each "screen" of their device. That can quickly get difficult and confusing if that user has a lot of apps.
My tweaked apps screen serves up more flexibility around organizing them. Imagine each screen represents a category of apps. When apps are downloaded from the App Store, they go to a default app category on the phone, but users can move them to alternate or custom categories. (Swiping sideways navigates between categories.) This removes the need for "folders" completely, which can limit how apps can be organized.
Apple's iTunes Store is nearing 50 billion ? billion! ? downloads. Here are the most-downloaded tablet apps ever.
