Renders Well … But
The app does most of the basic things it is supposed to: renders pages very well, is nimble, can download new books. But, if youre going to have a minimalist design, then you have to make it very easy to find hidden navigation. They spent all kinds of resources tweaking the page turning animation — but getting back to your library is still a gigantic hassle.
Somewhere, if you do something at the top, and the stars are aligned and the wind is blowing in the right way, and youve sacrificed honey and wheat to Demeter, you can get the navigation to pop up.
Otherwise, youre screwed.
