Fit screen when scrolling
As I scroll a PDF book, my up/down motion is not the only one. I zoom the page so that the text fills the screen and as I scroll, I must constantly recenter the page because you Neanderthals don't realize how a book is read. Why can't the screen lock to the text so that when I move up and down a text it doesn't also slide side to side? I always have to recenter. You ******* retards all probably use other reader apps that don't have this porblem because I'm sure it would have driven you nuts by now.
Angry OP is angry, but yes, I agree this feature would be really helpful for enhancing the reading experience not just on mobile, but also in your normal desktop app. Being able to lock the zoom so that scrolling a page thereafter didn't so easily turn into a panning side to side re-centering exercise as well would really help keep the user's focus on the document they're reading instead of on reading, scrolling, and then having to recalibrate to the center at their current zoom level.
See for instance I Amin chrome and when I scroll with my finger here, they are smart enough to only scroll vertically and keep the text columns centered on my screen. Why can't you do this also in the reader app? I want royalty if you implement this idea you ******* imbeciles
