Hello,

When scrolling one page down, it would be nice to have okular overlap and mark the last seen line in previous page, so that a visual cue is shown where one stopped reading (the last line in the current view). That would help a lot especially when the current view holds more than 50% of the entire page, and hitting PgDown overlaps many lines making it difficult to track the point where to restart reading.
Let's say I'm reading this:

"-4 blah blah blah,....
 -3 blah blah blah,....
 -2 blah blah blah,....
 -1 blah blah blah,....
 last visible line before PgDown"

and I hit PgDown. Then, in the following view (<50% of the full page content), I'd like to see a bright mark (highlight or whatever) over the "last visible line" (underlined in the example):

"-2 blah blah blah,....
 -1 blah blah blah,....
 last visible line before PgDown
 -------------------------------
 first line to restart with
 +1 blah blah blah....
 +2 blah blah blah"

Of course, if the following view has >=50% of the full page content, that would look like:

 "last visible line before PgDown
 --------------------------------
 first line to restart with
 +1 blah blah blah....
 +2 blah blah blah"

That would let me easily find the line "first line to restart with".
Ideally:
1) the highlight mark colour should be configurable;
2) the mark might fade away after X seconds, though just staying there until the next scroll event would be enough.

Cheers,

  ^s


Reproducible: Didn't try

Steps to Reproduce:
1) open whatever doc
2) zoom in to let <50% of the page in the current view
3) hit PgDown or scroll by mouse wheel

Actual Results:  
The "first line to restart with" is difficult to find in the following view.

Expected Results:  
The "last visible line before PgDown" as in the example above is highlighted.
