It seems that using PDFViewDual.vGotoPage(page) for
page = 0 or page = 1 will always show double page consist of page 1 and 2
but what if I have to have logic where I need the PDFViewDual show me page 2 and 3 ? Currently it doesnt seem to be possible, which is really surprising because if I need to show a magazine/news like view, those do not have double pages [1,2][2,3] but [2,3][4,5]. Imagine how stupid double page advertisement look using your solution, you have first page bundled to right side of previous double page and second page as left page of the following doublepage.
Would be really great if you could publish your View sources so that it is possible to alter the hardcoded behaviour instead of writing it from scratch which I will have to do probably now.
