We have been working on a new version of One Pager. To make it even clearer, it's now called Section Page.
Same formula as One Pager except a lot more complete and versatile. Section pages are now filled with 13 section types and countless settings allowing you to control margins, padding, colour and size of each section. One Pager was good, Section Page is better!
Give it a try in your admin panel: Create Page → Section page.
