Abstract: An electronic device: displays an interactive UI object that conditionally exhibits respective interactive behavior responsive to changes in detected contact intensity, and content that does not exhibit the respective interactive behavior. The device detects a first input over the interactive UI object. In accordance with a determination that the first input meets first appearance-manipulation criteria (e.g., an intensity of the contact exceeds a first intensity threshold), the device changes an appearance of the interactive UI object based on the intensity of the contact and independent of lateral movement of the contact. In accordance with a determination that the first input meets second appearance-manipulation criteria (e.g.

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.

In some embodiments, when a video is being played within a video document pane, a user can select the body of the video document pane to show the full content of the video document. Some embodiments provide a GUI that, when a user scrolls a video off-screen while the videos are playing inline in the document panes, pauses or stops the playback of the video and provides an indication that the playback is being stopped. In some embodiments, the indication is a fading of the video or of audio associated with the video, as the video document is scrolled off-screen.

Abstract: Some embodiments provide a method for rearranging a content layout. The method receives a first layout that includes content elements arranged across a first set of layout sections having a first number of sections, each of which has a same first width. The first layout defines a first margin width on either side of the layout and a first gutter width between the sections. Based on an available display width, the method determines a second gutter width and second margin width for a second layout based on the first layout. The method dynamically calculates a second number of sections in a second set of layout sections for the second layout based on the available display width, second gutter width, and second margin width. Each section of the second set has a same second width. The method rearranges the elements into a second layout that spans the second set of sections.
