Apple released a truly applaudable system improvement tonight: the iPadOS, which is independent of iOS, and Apple's system for the iPad, which is more in favor of desktop macOS usage.

The iPadOS has a denser home screen, with more icons per screen and permanent widgets, similar to desktop widgets, that can be pulled out by sliding left on the main screen. On the right side of the main screen, the message sub-screen can be displayed.

On the iPadOS, you can split views for each open App, create multiple working windows, press a task list or link for a long time, and you can drag it directly to other locations for new splitting or new windows. Screen splitting can be resized, multiple windows can be stacked, and multiple splitting can be done in the same App. Pictures, videos, links and text content can be dragged and pulled between multiple splitting screens, that is to say, multi-task execution can be realized in real sense.

Apple has also brought "desktop" browsing to the iPad, better compatibility with Web applications such as Google Docs or Squarespace, and new keyboard shortcuts and download managers to the iPad Safari.

The iPadOS refines the file management system. ICloud Drive now supports folder sharing, not just files. The new "file" application also uses a column view similar to macOS, with additional stored directories displayed in the "file" application.

The iPad now supports external USB and SD cards, which can be accessed only by inserting and using "file" applications. It's worth celebrating that for cameras, there's another way you like to start automatically, such as automatically starting third-party image editors commonly used by users after connecting to cameras, such as Lightroom.

The iPadOS adds custom font support, allowing users to download font libraries from the App Store. In addition, text editors on the iPad have new gestures, one is the cut, copy and paste of the three-finger gesture playback, and the other is the undo of the three-finger sliding. The iPad also has a new compact keyboard layout, which is smaller and occupies only a small portion of screen space, and can be dragged to other parts of the screen at will.

Finally, Apple emphasized the importance of Apple Pencil for productivity of the iPad. On the iPadOS, Pencil's latency dropped from 20 milliseconds to 9 milliseconds to allow more responsive interaction with digital handwriting pens. Handwritten tags are integrated within the system, so you can comment directly on screen shots or the entire document. Apple has also opened the PencilKit API for third-party applications.

As a new debut system, iPadOS should also push updates with iOS 13. You iPad users should be very excited. We will give you a more comprehensive overview after the arrival of the developer preview. In short, the advent of the iPadOS marks the iPad's move toward a more professional goal, closer and closer to the ideal of becoming a small portable computer.
