Abstract: A device implementing a system for obtaining a consistent state of data based on data updates made on different devices includes a processor configured to generate, for a first data update, a first data model including first data nodes, each including a first identifier and a first data value corresponding to one of first data objects. The processor is configured to receive from a second device, for a second data update to the data, the second update being independent of the first update, a second data model including second data nodes, each including a second identifier and a second data value corresponding to one of second data objects. A consistent data model is obtained by merging the first and second data values with the same identifier, and then merging the first and second data models, and generating a final update of the data based on the consistent data model.

Abstract: A method includes displaying a drawing aid in a sketch area on a touch-sensitive display, and receiving one or more drawing inputs. In response to receiving the one or more drawing inputs, the device displays marks based on the drawing inputs that are constrained based on the drawing aid. While displaying the drawing aid in the sketch area, the device detects a touch gesture at a location corresponding to a location of the drawing aid. In response to detecting the touch gesture: if the touch gesture is a pinch gesture, the device ceases to display the drawing aid in the sketch area; and if the touch gesture is a rotational gesture, the device rotates the drawing aid relative to the sketch area in accordance with the movement of at least one contact in the touch gesture while maintaining display of the drawing aid in the sketch area.

Abstract: Various techniques are disclosed for managing and modifying data items.

Thereafter, subsequent data items can be selected for password protection using the same set of user credentials while the secured user session remains active. In some embodiments, a gesture input can be received by a touch interface. The input can be detected, and when the input is recognized as a command for creating an extension of a work space associated with a data item, then the extension of the work space is generated. In some embodiments, the gesture input received by the touch interface is recognized as a command for creating a new work space associated with the data item such that a new work space is generated upon recognizing the input.
