No ability to scroll, significant lack of features

Is there any possible way for Adobe to make the Adobe Digital Editions product even close to as functional as the Calibre ebook reader on PC? This user interface is garbage, the lack of scrolling is horrible, the side to side page turns suck, even as a kindle competitor I've found that most ebooks on this platform lack polish.

What is going on here? Am I the only person that sees these issues?
