After 3 years Nomad Reader finaly got an update! I open sourced it on GitHub and now its code was modified byIvan Ivanenko, author of great e-book reading app Libri eReader: https://play.google.com/store/apps/details?id=com.foobnix.pdf.reader

Changes:

- Android 6.0 support

- clicking on the center of the screen opens the menu

- broken books would not be re-opened on the next start

- adaptive font scale (not it is bound to device DPI)

- fb2.zip opening from other applications
