Highlighting by expanding the pins is tricky and awkward -- its hard to get them exactly where I want them and not a word further. And then requires a second step -- clicking on highlight. The Kindle app does it much more elegantly -- press and hold where you want to begin, drag to where you want to end, release and the highlight is done.
Also, you should give us the option (again, like the Kindle app does) of choosing among several highlight colors. Ive looked for a way to change the color. If there is one, its not easily found. With Kindle, the option is right there when you highlight.
