The actual search and display of the highlights in the grid seems fast enough. 
However when I navigate to a page from the search results, the performance 
drops big time.  Something about the highlighting withing the normal page view 
seems to slow it down a lot.

Scrolling and flipping pages is a lot faster now. Feels pretty good! Zooming is 
still quite slow, though.

Now that the page does not move sideways while scrolling down if it fits the 
page, scrolling works a lot better. Great work!

Flipping pages feels better as well. However I still quite often swipe too 
little so the page snaps back into place rather than switching. Also a few 
times I had to look at the page content to see if it actually switched or not. 
The animations of a page snapping back when it wasn't flipped and the actual 
flipping seem a bit hard to differentiate sometimes.

Notice that the fact that I'm already talking about UX details is usually a 
good sign, because that means that the basics already work well and we are on 
the way from good to great experience!

Keep up the good work,
Thomas
