  • Patent number: 9836190
    Abstract: A user interface that displays a number of cards or windows is described where a user can move the cards in a horizontal direction freely. When a card resides in a locked zone, as defined by a user, the card will be able to be manipulated in a vertical direction, while cards that reside in a regular zone will not be able to be moved vertically. In addition, only cards that are in the locked zone can be subjected to a user action such as cutting content from the card, pasting content to the card, enlarging the contents of the card, or shrinking the contents of the card.
