Less ‘Bulky’ UI
While iOS is pretty clean and intuitive, there are certain aspects of its user interface that are undoubtedly clunky. Just think of the volume HUD prior to iOS 13. Or the fact that both phone calls and Siri commands take up the entirety of the display. Apple should fix this.
Siri responses could appear, just as an example, in a notification-style banner at the top of the screen. You could glance at it and flick it away if Siri’s voice response answered you question. If not, you could drag the pane down for a full-screen view of information.
