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.
