, thank you very much for the instructions. But I'm afraid my point is slightly different: I am intensively using that function and I have to say it's a very smart ingredient of the reader. However:
1- What you mentioned above doesn't work (or at least I couldn't) when one zooms out of the default size, it has only worked for me when I have zoomed in enough so that some width of the page is not contained in the display's; that's why I brought up the "Center View" subject.
2- By continuous page shifting/scrolling I meant pretty much the same thing that is common on DJVU/PDF readers on computers: you can have the bottom of one page plus the top of the next in the same screen. This, apart from saving you/yourtime/device from pressing one more button per 2/3 pages, gives you the ability to have an eye on the first part of your incomplete sentence from the last page without the need to press two additional keys. This specially becomes important when you are trying to follow a logic of some kind.
3- Another great function the reader could have is to "Fit Visible". Acrobat Reader has this function, but it is more meaningful/desirable to have it here on small devices rather than computer screens. It automatically zooms in so that the side edges of the text are (almost) touching those of the screen's. For this of course the program needs to recognize the redundant white space (something like what croppers do) and adjust the zoom accordingly (auto).
