First sorry for my english...
My concept is called "Paperfold reader". As you can imagine everything is based on the "paperfold transition effect".
The interface of the reader will have 3 sections:
1-for the list of feeds2-for the list of articles of the feed selected3-the articleOn the desktop the 3 sections can be deployed at the same timeOn the tablets you will probably have 2 sections at the same timeOn mobile 1 section at a time
There is no "menu" or "home" button you just have to swipe left or swipe right to fold the section and view an other.
