Abstract: A method for controlling screen rotation of an electronic reading device that includes processing circuitry, an accelerometer, and a display screen. The method including: receiving, by the processing circuitry, a request to access a menu for initiation of a screen-rotation lock function for the electronic reading device; displaying, on the display screen, the menu for the initiation of the screen-rotation lock function; receiving, by the processing circuitry, a selection of one particular screen orientation for the display screen from among a plurality of screen orientations; rotating, the electronic reading device, 90 degrees; detecting, by the accelerometer, the 90 degree rotation; and maintaining a screen that is displayed on the display screen in the selected one particular screen orientation.

Abstract: A method for annotating dynamic content includes receiving a freeform annotation overlaid on dynamic content; determining whether the dynamic content changes; in response to a determination that the dynamic content changes, displaying an indicator corresponding to a region where the freeform annotation was created; determining whether the indicator is selected; in response to a determination that the indicator is selected, displaying a lightbox with the freeform annotation as it was overlaid on the dynamic content when it was created; determining whether the a revert button included in the lightbox is selected; and in response to a determination that the revert button is selected, displaying the freeform annotation overlaid on the dynamic content as it was created before the dynamic content changed.
