Paging would be desirable. However, FBReader doesn't do paging. The closest it comes to it is starting a chapter heading at the top of the screen (with some formats).
Edit. More on paging: I don't know what rendering engine they use, but MS Reader figures out the paging of an ebook when it is first opened. This of course depends on screen size, font, font size, etc. You can start reading a book while the paging is being done in the background. As long as you don't try to jump to the end of a very long book before the process is finished, this method works very well.
