Abstract: Some embodiments provide a document viewing application with first and second document channel browsing modes. The first mode displays selectable items corresponding to document channels. Selection of an item causes the application to add the corresponding document channel to a set of selected document channels from which to retrieve documents for presentation within the application and dynamically add items corresponding to document channels related to the selected document channel to the selectable items for display in the first mode. The second mode displays a first set of selectable items corresponding to sources of documents and a second set of selectable items corresponding to document topics. Selection of an item in the second browsing mode causes the application to add the corresponding document channel to the set of selected document channels and modify the selectable items presented in the second mode a next time the second mode is entered.

Abstract: The present disclosure generally relates to displaying content. The method includes displaying a portion of content and while displaying the portion of the content, detecting first movement that includes movement in a first direction.

After scrolling the content to reveal the second portion of the content, the method includes detecting a second movement. In response to detecting the second movement, in accordance with a determination that the scrolling of the content met content locking criteria, the methods includes maintaining display of the content without displaying a second content, and in accordance with a determination that the scrolling of the content did not meet the content locking criteria, the method includes switching from displaying the content to displaying the second content.

Abstract: Some embodiments provide a document viewing application with first and second document-browsing modes. The first document-browsing mode, accessed through a first UI item of several top-level UI items, displays several selectable document channel items corresponding to previously-selected document channels. Selection of one of the selectable document channel items causes the document viewing application to present a set of documents related to the document channel corresponding to the particular selectable item. The second document-browsing mode, accessed through a second UI item of the several top-level UI items, displays several selectable document panes corresponding to documents related to several of the previously-selected channels.
