Disclosed are implementations of methods, apparatus, systems, and computer-readable storage media for rendering information. In some implementations, user interface data including content capable of being displayed on a page is received. A dynamic window including one or more link linked with respective identifiable portions of the content on the page can be generated. The page of content and the dynamic window can be displayed in a user interface on a display of a computing device. The user interface can have a first state in which a first view of the page of content is displayed and a second state in which a second view of the page is displayed, where the second view is different from the first view. The dynamic window is capable of remaining displayed independent of a change of the user interface from the first state to the second state.
