Apple in iOS 14.3 is streamlining the Home Screen customization process by simplifying the way that app shortcuts work. With the launch of iOS 14, users quickly discovered that Shortcuts could be used to replace traditional app icons to create an entirely customized Home Screen look.
Unfortunately, while these Home Screens created with Shortcuts looked fantastic, the experience was less than ideal because launching an app through shortcuts required the Shortcuts app to open briefly, slowing the app opening process. In iOS 14.3 beta 2, that's no longer the case because shortcuts no longer have to route through the Shortcuts app.
Such a small change, but yet this is going to make a massive difference. Custom home screens are the thing now, and major component of that is using Shortcuts to create custom app launchers. And until 14.3, they require Shortcuts to open before running the shortcut. But with this change, they’ll start to look and feel like real apps.
I like how Apple have been slowly integrating Shortcuts into the system. Bit by bit, iOS is becoming more customisable, allowing users to really make their devices their own.
