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.
1. A method programed into instructions to be performed by a computing device, the method comprising:
displaying, within a graphical user interface of the computing device, a plurality of messages that belong to a hierarchy of messages;

displaying messages that are descendants, in the hierarchy of messages for the particular discussion thread, of the root message.
8. The method of claim 1 , wherein displaying the second set of messages that are descendants, in the hierarchy, of the second message comprises causing one or more visual representations of at least the second message and the second set of messages to occupy the space, within the graphical user interface, previously occupied by visual representations of the one or more messages that were previously displayed.
9. The method of claim 1 , wherein the second message is an indirect child of the first message within the hierarchy of messages.
10. The method of claim 1 , wherein the one or more messages includes at least the first message.
11. The method of claim 6 , wherein displaying the shortcut to the list of the plurality of related discussion threads further comprises displaying a visual representation of the shortcut above a visual representation of the focal message within the graphical user interface.
