iPadOS 13 dramatically improves the productivity of the iPad and it starts with the home screen. You can now pin the Today View widgets to the left column on the tablet’s home screen, making it much easier to access your favorite shortcuts.
How to Access Today View in iPadOS 13
The Today View used to show up as its own page on the iPad. In iPadOS 13, it shows up as a column on the left edge of the iPad’s screen. Just swipe right anywhere on the left-most home screen to reveal the widgets panel.
If you’re in the landscape mode, the icon grid will shrink to take up space next to the Today View panel. Swipe left to hide the panel. If you’re in portrait mode, swiping right on the home screen will bring up the Today View panel on top of the home screen (the icons will be blurred).
How to Add Widgets to Today View
If you’re new to using the Today View, you’ll first need to add widgets to this screen. Scroll to the bottom of the Today View section and tap on “Edit.”
You’ll now see a list of all enabled widgets. They’ll have a “Minus” icon on the left edge and a “Handle” icon on the right edge. You can tap on the “Minus” button and then tap on “Remove” to remove the existing widget from the Today View.
