I am looking for a pdf reader which meets these requirements:
1- Open pdf starting from last page opened during last session
2- Be able to scroll between pages vertically (not horizontally like many current ones) do. Vertical scroll should be a continuous smooth scroll without doing a sudden full page pull in. Should behave as if pdf is one single very long page.
3- Should be able to change width of page and lock it. Page should not move sideways. Page width should be remembered so when same pdf is opened, it opens in that width.
4- A fast scroll feature. Useful for pdf's with hundreds of pages.
5- Nice to have feature: when opening the pdf reader, it automatically opens the last pdf file on the last page read.
I have tried all the free pdf readers in the AppStore and none met all these requirements except for two which had these issues:
1- iRead limitation: When screen is touched for more than a second, the page is frozen (locked) and page can't be scrolled. Scrolling is done when doing quick swipes only
2- FileApp limitation: Does not remember last page opened. Does not remember last width set. Fast scroll doesn't work properly when width is other than default.
