content: Smooth scrolling operation. Shows you a full catalogue of what PDFs you have on your devices. Has a robust AMOLED night mode with highlighting features. And these are just to name a few. Edit I removed two stars just because when I download a PDF file using Adobe Reader in certain apps it saves the file somewhere in the storage where I cant access it from my file manager. I can only access it with the App. Even then there is no way to move the file somewhere Id like to.
