Slide Over is a multitasking feature found in iOS devices that allows users to access a secondary app without leaving the primary app. This feature enables a more efficient workflow by letting users quickly switch between tasks, enhancing productivity on tablets like the iPad. When using Slide Over, the secondary app appears as a narrow panel that can be easily swiped in and out of view. This design allows users to interact with both apps simultaneously, making it ideal for tasks such as referencing information while writing or chatting while browsing the web.
