This is not
what you are looking for but perhaps a little help:
If you shortly press the on/off button a menue opens with some functions (for instance making a screenshot) and the list of the ten last opened books. You can open the books from there. For changing between books very often this is the quickest way (assumed the book you want to open is amongst the last ten).
