Stacking Widgets
There’s also a special widget, which Apple calls the “Smart Stack” which will display multiple widgets in a single panel. This is a medium-sized widget by default, and Apple promises that it will also update to show you the most appropriate information during different times of the day, such as displaying your morning news feed when you wake up, and your calendar when you’re ready to start work.
However, you can also create a stack for any set of widgets that are the same size simply by dragging them on top of each other, just like you would to create a folder of apps. The widgets will merge into a stack and you can swipe up and down to see the different ones, and it will even act like a Smart Stack too. Tapping and holding to bring up the context menu for a stack of widgets will offer an “Edit Stack” option to let you reorganize the widgets that are in the stack, remove any you no longer want there, or turn off the “Smart Rotate” option to stop it from behaving like a “Smart Stack.”
