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: Some embodiments of the invention provide a novel method for generating a page that contains summaries of a number of documents. In some embodiments, the page includes several sections (e.g., rows). The method receives a set of documents to summarize. The documents in the received set are sorted in an order (e.g., based on relevance to a viewer of the page). In some embodiments, the method uses a layout generator to identify an arrangement of one or more document summaries for each section on the page.

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.
