Recently Hitch asked me why I need fixed layout. As I currently don't use pop-up views, the reading experience was my main issue: you have to double-click an image before pinch-zoom starts working, this gets annoying pretty quick.
Well, today I checked a book in reflowable format on my android phone and Android tablet, and the pinch zoom now work without double-clicking! I'm sure this wasn't the case a few weeks ago. So this is either a coincidence or programmers from Amazon read this forum, and respond constructively, and they updated Android Kindle app. This is actually a very good news.
Now, dear Amazon programmers, could you apply the same fix to e-inks? The problem remains on my Paperwhite with reflowable format.
Another request to Amazon:
Could you enable internal hyperlinks (and htmltoc links) in fixed layout on e-inks? Or at least make the hyperlinks passive, i.e. do nothing in e-inks. Currently, on Paperwhite, clicking a hyperlink in fixed layout moves to the very next page, no matter which item of htmltoc you click. This would be so helpful.
