As usual, although iPadOS and iOS are in the same department, the iPad is still different enough for Apple to introduce it separately at WWDC. The most important change among the new features is that Apple has once again changed the way of multi-tasking. Now as long as you slide down from the top of the screen in any app, a “multitasking menu” will appear, and you can choose whether the current app is displayed in full screen, bisecting, or floating. A separate window will have an area called “the shelf” at the bottom of the screen, allowing you to quickly exchange apps. iPadOS 15 also adds keyboard shortcuts to help you quickly switch between multiple windows.
The second obvious big change is that the Widget can be placed anywhere on any page of the main screen, instead of hiding on the side of the first page, and with the large screen of the iPad, it brings a new large-size widget. iPadOS has also added the App Library function that was only available on the iPhone before, allowing you to reduce the amount of page usage.
In addition to adding @ an object to Notes itself, adding them to the editing ranks, it also adds a new activity viewer to see all the activities on the shared note. Hashtag tags are also introduced in Note, and you can quickly find related notes through the tag browser. In addition to the Notes app itself, there is also a new tool called Quicknotes, which can slide out a note for notes at any time from the lower right corner of the screen. This sticky note can leave a link to the app (or a web link in the case of a browser) according to the app you are currently using, or it can leave multiple app links in the sticky note to form a work plan .
Although iPadOS has always been the main multi-tasking possibility, the multi-function function so far has been incompatible with the overall user experience, as if it was a hard case. Whether iPadOS 15 can change this and make iPad Pro truly a productivity tool that can compete with PCs, is the next time that iPadOS 15 goes online. There is no information on when iPadOS 15 will go live, but based on past experience, it should come around September.
