I prefer to keep the paragraph I'm currently reading centered on the
screen.  It "gives me context", so to speak.

This does make it easier to scroll.  However, it seems to remove all abilty
to move the cursor.  Up and down scroll up or down one line, dragging the
cursor with them if it'd go off the screen, while left and right seem to
scroll up or down an entier page at a time.

(I also managed to get it to segfault.  I'll send the bug report in a
minute.)
