What if we could define areas of the page to do certain tasks when tapped (when no tool is active)? For example,
– page forward/back, first page, last page, go to page;
– browse thumbnails in all/annotated/bookmarked mode;
etc. I’m using this in EbookDroid; in that app, the left edge of the screen goes a page forward (because I’m holding the tablet in my left hand), the top left corner goes the first page, the bottom center closes the book, and so on. This is configurable in EbookDroid, and I imagine it configurable in Xodo, too.
Currently, the left and right edges are for paging, and the rest is to toggle view mode. This is nice, but it could do more.
