iOS 9 wishes

Federico Viticci's iOS 9 wishlist contains my number one gamebreakinig missing feature in iOS:Seven years into the App Store, I struggle to find a reasonable motivation for not allowing users to set different default apps on iOS. I believe Apple should accept that they can't make the perfect email client or web browser for all kinds of users, and, just like custom keyboards, they should let users choose their favorite app for a specific set of core tasks. If personalization of a user's iOS device has truly become a priority at Apple, then it should be extended to activities that users frequently perform on an iPhone or iPad.If Apple were to finally make this possible, there's going to be a whole lot of Google iPhones and Google iPads out there.
