The most significant user-requested update of the new firmware version 5.4 is the implementation of the new PocketBook interface designed with a single purpose - to make using the e-reader even more convenient. Main page which is loaded when the device is switched on is now a Library. Books are placed in the order of demand – current books are listed above and recently downloaded - under them. Active zones in the lower and upper parts of the screen allow users to access the main menu items quickly. Additionally, notification services have been redesigned and are now more informative and comfortable.
