Some question:
- Does koreader use A2 refresh mode? I am asking about this because builtin apps have faster and better scrolling. In builtin apps when scrolling page is displayed in black and white (high contrast, no grays), and scrolling is fast. In koreader grays are still displayed when scrolling and it is slower.
- Is there any way to go back from filebrowser to already opened document without selecting any file?
