iOS Resizable App Icons Concept. Inspired by the more living home screens of Windows Phone and Android, this concept video shows how the iOS home screen could become more. 

In this concept, an app icon can be resized from 1x1 to 2x2 or 4x2, similarly to how you would on Windows Phone 8. The increased size can house widget like functionality and provide easy access to core features of that particular app. For example, you could expand the Settings icon into a widget with a brightness slider, and quick toggles for WiFi, Bluetooth, Personal Hotspot and Do Not Disturb. 

The newfound space could also be used to give a miniaturized window into the app, showing content already on the home screen. This could be useful for Phone, Messages or Mail. Instead of a glaring red badge, you’d be able to see the messages or calls directly on the home screen.

To launch the app, you can press the shrunken app icon in the lower left. 

The expanded icons can be moved around like regular icons and placed in the manner you like. But for obvious reasons, you cannot place an expanded icon in the dock; it would just slide back onto the home screen. 

One could imagine that this functionality would also be available to developers, who could include it for their apps.

This would rather nicely complement the existing feature set of iOS and make the home screen more engaging.
