â€¢ Lockscreen with time, date and notifications
â€¢ Start screen with familiar blue tiles and links (hopefully customizable)
â€¢ Profile settings (WiFi and volume settings)
â€¢ Transitional animations
â€¢ Pictures Hub
â€¢ Games Hub (probably to hold all your games)
â€¢ Media Hub for music, video, podcasts, radio
