Hierarchy-Indicating Graphical User Interface For Discussion Threads
Techniques are described for display and navigation of hierarchical messages, which displays include contextual data for the messages. Context information for a current message includes reply messages, parent messages, and metadata representations. Message representations are also associated with visual depth indicators that are independent of the text of the messages. Users may navigate displays of hierarchical message data using different navigational inputs. For example, more information may be requested for messages, without selecting a new message for viewing as a focal message, using swipes across portions of the display dedicated to displaying the messages. A limited number of messages for a requested list of messages is initially retrieved and displayed, and a mechanism for viewing more messages from the list is provided. Historical usage of the mechanism is recorded and the number of messages to be displayed for the list of messages is adjusted based on the historical usage data.

9 . The computer-executed method of claim 1 , further comprising:
in response to selection of a message shortcut, performing the steps of:
establishing a third message, referred to by the message shortcut, in the hierarchy of messages as the focal message;
ceasing to display messages, within the graphical user interface, other than the third message and a third set of messages;
wherein ceasing to display messages other than the third message and the third set of messages includes ceasing to display at least a fourth message that resides below the second message in the hierarchy;
wherein the third set of messages reside below the third message in the hierarchy.
10 . The computer-executed method of claim 1 , further comprising:
in response to detecting a particular type of device motion of the computing device, including the graphical user interface, after establishing the second message as the focal message, performing the steps of:
establishing the first message as the focal message; and
ceasing to display all messages, within the graphical user interface, other than the focal message and the first set of messages.
11 . The computer-executed method of claim 10 , wherein the particular type of device motion comprises a shaking motion.
