On the home screen/page click on and hold any application/widget. Once you have the widget drag it to the far right side of the screen but do not let go until a new page has been made available. Drop the application onto the new page. Just like that a new page has been created now load the page up with what you want and return the app/widget you use to create the page back to its original location. You can also stack applications /widgets into a folder making room for even more applications or widgets, just place one app/widget on top of one another. Organize your folders by categories such as videos, photos and music or Instagram, twitter and Facebook... I hope this helps.
I believe the max # of screens is 5-7. After that, you may need to resize some widgets and remove any app shortcuts or condense them. If nothing else, app shortcuts are always in the app drawer.
The left page from Home is for your most used application or folder of applications. I use mine to access music but it would be a great place to construct a shrine to the one you love.
