Messages are presented so as to make effective use of the display area to convey information to the user. For example, message content of primary interest to the user (e.g., new content) can be distinguished from secondary content (e.g., content quoted from a previous message), and the message can be initially displayed with the secondary content hidden using an expandable visual indicator that the user can expand to reveal the secondary content. Different elements within a message, such as textual content and graphical content elements, can be scaled independently using magnification factors optimized for each element.
