Apple has announced iPadOS 14 with new design language for apps, Siri improvements, redesigned call interface, home screen widgets, better search and much more. The announcements were made at the virtual WWDC 2020 conference today.

iPadOS 14 features a new design language, which relies on sidebars to organize most sections and features in an app, similar to how Files app works. The sidebar items support drag and drop for easy content management.
