When I'm reading an ebook I often find myself looking where to continue. I mean this:
1. I read untill the last word on my screen,
2. then I scroll with my mouse (once or twice) and the text moves up for a number of lines,
3. consequently me eyes go upward to look for that last word, in order to continue reading.
This is annoying. I would like to have a visual indicator where I have to continue reading. For example a small line between the old and new lines, or a (temporal) highligt of the first new word.
Now I don't know if this should be a plugin or a feature of the main program. This is my first post on the forum. But I guess this place on the forum is a promising one

If such a feature already existst, please tell me. I could not find it anywhere.
