Abstract: Various features and processes related to document collaboration are disclosed. In some implementations, animations are presented when updating a local document display to reflect changes made to the document at a remote device. In some implementations, a user can selectively highlight changes made by collaborators in a document. In some implementations, a user can select an identifier associated with another user to display a portion of a document that includes the other user's cursor location. In some implementations, text in document chat sessions can be automatically converted into hyperlinks which, when selected, cause a document editor to perform an operation.

Abstract: An electronic device with a display, a touch-sensitive surface, one or more processors, and memory detects a first portion of a gesture, and determines that the first portion has a first gesture characteristic. The device selects a dynamic disambiguation threshold in accordance with the first gesture characteristic. The dynamic disambiguation threshold is used to determine whether to perform a first type of operation or a second type of operation when a first kind of gesture is detected. The device determines that the gesture is of the first kind of gesture. After selecting the dynamic disambiguation threshold, the device determines whether the gesture meets the dynamic disambiguation threshold. When the gesture meets the dynamic disambiguation threshold, the device performs the first type of operation, and when the gesture does not meet the dynamic disambiguation threshold, the device performs the second type of operation.

Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for displaying display primary e-book content, note glyphs and margins in an e-book interface according to the size of the e-book interface; animating “peeking pages” and glyph size during and after re-sizing events; selecting text in an e-book, entering a note that will become linked to the selected text, and representing the presence of the note on top of the primary content of the e-book as an interactive glyph according to some embodiments of the present technology; and displaying note objects, editing note objects, and navigating between note objects in a note-view pane of an e-book interface according to some embodiments of the present technology.

Abstract: Some embodiments provide a GUI for a document reader application for viewing videos in video document panes. In some embodiments, the GUI determines whether to play the video inline within a document pane based on the size of the video document pane. 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: Various techniques are disclosed for managing and modifying data items. In some embodiments, a first data item can be selected for password protection via establishing an active secured user session according to a set of user credentials. Thereafter, subsequent data items can be selected for password protection using the same set of user credentials while the secured user session remains active. In some embodiments, a gesture input can be received by a touch interface. The input can be detected, and when the input is recognized as a command for creating an extension of a work space associated with a data item, then the extension of the work space is generated. In some embodiments, the gesture input received by the touch interface is recognized as a command for creating a new work space associated with the data item such that a new work space is generated upon recognizing the input.

Abstract: An electronic device with a display and a touch-sensitive surface stores a document having primary content, supplementary content, and user-generated content. The device displays a representation of the document in a segmented user interface on the display. Primary content of the document is displayed in a first segment of the segmented user interface and supplementary content of the document is concurrently displayed in a second segment of the segmented user interface distinct from the first segment. The device receives a request to view user-generated content of the document. In response to the request, the device maintains display of the previously displayed primary content, ceases to display at least a portion of the previously displayed supplementary content, and displays user-generated content of the document in a third segment of the segmented user interface distinct from the first segment and the second segment.

Abstract: An electronic device simultaneously displays on a touch-sensitive display a first user interface object and a second user interface object. The second user interface object has formatting attributes, one or more of which are distinct from corresponding formatting attributes in the first user interface object. The device detects a first contact on the first user interface object and a second contact on the second user interface object. While continuing to detect the first contact and the second contact, the device detects movement of the second contact across the touch-sensitive display, and moves the second user interface object in accordance with the movement of the second contact. The device changes one or more formatting attributes for the second user interface object to match corresponding formatting attributes for the first user interface object if the second user interface object contacts the first user interface object while moving.

Abstract: An electronic device with a display and a touch-sensitive surface displays a page of a first multi-page section of a document and a navigation bar configured to navigate through only pages in the first multi-page section of the document. The device detects a predefined gesture at a location on the touch-sensitive surface that corresponds to a predefined portion of the navigation bar. In response to detecting the predefined gesture, the device displays a navigation user interface that enables selection of a page of the document that is outside of the first multi-page section. The device receives an input in the navigation user interface that indicates selection of a page of a second multi-page section of the document outside of the first multi-page section. In response to receiving the input, the device displays the selected page of the second multi-page section of the document.
