Two audiences for this video:

If you are new to iPad multitasking, or if you’ve been confused by the interface, or support someone in one of these categories, the video below is a brilliant explainer.

If you are a regular user of the three dots Split View interface, the first half of the video will be old hat to you. But watch the video anyway, stick around for the second half. It dives a little deeper, into the subtlety of opening (in this case), multiple notes at once, organizing the notes you have open.

Another well done video from the Apple Support team.
