Instead, there is a "vertical scroll lock" option. This locks the scrolling to be only vertical, unless you make a serious (1/5 screen width) swipe left or right which temporarily unlocks horizontal scrolling.
I read many books, not available as pdfs, that I buy and scan. I therefore have two requests, if I may, regarding scrolling.
I would like a horizontal scroll lock very much, as I scroll horizontally. Sub-request, many books I read are Japanese, thus it'd be great if one could have a setting for horizontal scroll direction, left to right, and right to left.
Anyhow horizontal scrolling currently doesn't seem to work at all, though you mention that making a horizontal motion 1/5 of the screen should do it, doesn't do anything for me.
Second request, very important, scrolling page lock. Now, pages just roll based on how you flick the finger, no way to just flip to next page. Furthermore, as I scan the books myself, they don't have a uniform page size, and it's very uncomfortable to see parts of other pages on the screen too.
Last, minor, not related to scrolling, can you add yellow text on black background to the invert colors option. I prefer it over green.
Thank you and many thanks for your efforts in developing this app.
Best regards,
