In Android and some eInk readers like Boox, there exists an auto-crop functionality that “cuts” all the blank around the PDF, with an effective zoom of 100% only text. The quality of that zoom varies between completely unusable and very usable. As summary of features, you can find auto-crop at each page level, same manual crop ("the rectangle of @jowett) for all pages or for odd and even separately, and a last one that is going with same zoom level when changing page in one page mode. I think the old GoodReader app in iOS has some of those features, and I thought about asking you about those, but there is an easy workaround in DTTG: set in continuous mode, make a manual zoom, and scroll. Potential issues happen when the margins are different in even and odd pages.
