adding navigation button like next previous

[Just-some-one]

Hello

i think adding next and previous button to the top and bottom of the books and guides sections so user can go to the next page of what he/she reading without the need to go to the navigation menu

it would be nice also to add short key (maybe key event listener for left and right arrow ) to go the same as the buttons

thanks for your great work and have a nice day :)
