Painful and unintuitive

This app is the mandatory ereader for the CFA books and it is terrible. It lags, always displays a graphical overlay at the bottom of each page, it has a bad index/reference system. In the end I had to just use the hard copies to study, you end up spending more time fighting the UI than you do reading/studying.
