Instead of being laid out in fixed pages, everything becomes a single scrollable column of text and images, with an outline that lets you tap to jump from section to section. In short, it moves beyond the tyranny of a particular document size and makes PDFs feel more like web pages. (Web designers solved this issue years ago with responsive design, which lets websites rejigger themselves on the fly for screens of any size.)
About time haha
Buti naman. Its not funny when you have to expand pages to make them readable, and you end up missing what you are reading kasi confusing where you were.
