1) I checked, that is why I posted this report again

2) me too, but here is hard to do it, because you would have come up with some
smart limit how many pages okular should prerender (IOW, I am out of better
ideas). So it is not that I like the options, but when I don't see really smart
behaviour on horizon, I simply rely on them to provide needed level of
customization.

One I have maybe, but it is complex:
a) minimum, one back, one forward prerendered page
b) check if user waited for N-th page, if yes, extend the limit to N (up to
available memory)

So for example, I am on page 10, I pressed 5 times pgup fast, okular notices it
has to extend the limit from 1 to 5. When I am reading page 5, the cache is
build for pages 1-4, 6 (this limit is not changed), plus they are remembered
pages: 9, 10, 11 (from previous position).
