In addition, in response to a second user input to move from the first content item to a second content item, automatically collapsing the series of images to display the pile of stacked images associated with the first content item before displaying the second content item.

Abstract: Particular embodiments arrange a plurality of objects in a hierarchy, the hierarchy having one or more layers and each layer having at least one of the objects; display a portion of a sequence of first objects on a screen of a user device, the sequence of first objects all belong to a first layer in the hierarchy, each first object having as its children one or more second objects belonging to a second layer immediately below the first layer in the hierarchy; in response to a user scrolling through the sequence of first objects, estimate which specific first object in the sequence the user is likely to be viewing at a predetermined time in the future based on an acceleration of the user scrolling through the sequence of first objects; and preload the second objects that are children of the specific first object.

Abstract: In one embodiment, a plurality of content items is displayed. The content items are of a plurality of content types. In response to a user selecting a specific content type, only those content items of the specific content type are displayed. In response to the user unselecting the specific content type, all the content types are displayed.

Abstract: In one embodiment, a method includes creating and presenting a first content item for composing by a user; presenting a plurality of icons respectively representing a plurality of content types; in response to the user selecting a specific icon representing a specific content type, presenting a plurality of second content items of the specific content type; and in response to the user selecting a specific second content item, incorporating the specific second content item into the first content item.

Abstract: In one embodiment, a method includes while a user is interacting with a mobile device, displaying a notification on a screen of the mobile device automatically and without any user input to the mobile device, the notification informing the user an event that has occurred recently and is not related to the user's interaction with the mobile device.

Abstract: A method is performed at an electronic device that includes a display, a touch-sensitive surface, one or more processors, and memory storing one or more programs. The device displays a user interface of a software application, wherein the user interface includes a plurality of user-interface elements. A first gesture is detected on the touch-sensitive surface while displaying the first user interface, and an initial direction of movement is determined for the first gesture. The device recognizes that the initial direction corresponds to one of a first predefined direction on the touch-sensitive surface or a second predefined direction on the touch-sensitive surface, wherein the first predefined direction is distinct from the second predefined direction. Display of one or more user-interface elements of the plurality of user-interface elements is manipulated in accordance with the corresponding one of the first or second predefined direction.
