I use the Kindle app a lot, and it drives me cranky. First the pros. It lets me carry a whole library with me; and it syncs across devices. So I can highlight and annotate on one device, say my Mac. and my changes are there when I open it on my iPad, or indeed a kindle reader. All of that is really useful.The *cons*: I often want to highlight and annotate a text. That’s where the problems start. Whenever I select text, three dialogue boxes open whether I want them to or not: a dictionary definition; a wikipedia link, and a translation. I can imagine all of them could be useful sometimes, but they’re worse than useless if they happen every time. I really don’t need them every time I select text. i usually know what a word means; I don’t usually need to see what wikipedia has to say about the text I’ve selcted, and I never, never, need to translate. They take up room on my screen, and get in the way of my work. Maybe you can switch them off, but if so I can’t find how to do it.Second, selecting text is frustratingly random. Sometimes if I click on a highlighted word, it selects the whole highlighted phrase (which is what I mostly want it to do). Sometime it just selects a word. if it selects a word, sometimes a second click will then select the whole highlight. Sometimes it just deselects the word and the highlight. i’d love it if the same command did the same thing every time. Again maybe the behaviour is more regular and predictable, but if so, haven’t managed to figure out how.
