Having said that it's not at all intuitive how those settings really affect the result, I don't know how to check which mode ("page" or "scroll", "comic" or "paper", "auto crop" or "two-point") is actually activated at the moment - and that's a real GUI fail... I hope this is worked on.
EDIT: Referring to what Booxtor said, auto crop actually changes the page itself (internally without touching the document file), whereas zooming only affects the viewport. But in that case, after cropping, chosing "zoom to height" should only adjust the viewport such that the cropped page's height fits perfectly into the viewport. But this is not what happens: It usually zooms out so much that I get a margin of at least two cm around the whole cropped area. That's not logical, is it?
As I already said in some documents "auto crop" in "page settings" could have some problems to detect margins properly (it might be because of colored background, images, lines, "dirt" etc.) this is why we have add custom margins. If you just would give me some pages of your PDF file, so we could figure out what is wrong with, we could try to optimize "auto crop" for files like yours. Actually we have tested this function with lots of different PDFs and the final algoritm was polished and did work for all of that files.
We have also tried to keep the software being both flexible and intuitive. If you have ideas, what could be done to go further with optimization of intuitive GUI of it, you are welcome to share your ideas..
