Well, amigas, I'm convinced that reading along with the audio first time through is better than listenting without reading. With listening only, as soon as I hear a word I don't know, I'm distracted and it takes a couple more words to get back to comprehending the audio and if there are several new words it's a confusing mess!
When I read along with the audio the first time through I see the unknown words and know what to look for when I read it through without audio and do the pop up translations, then, next time as a read-along, it all makes sense.
I'd still like to have a speed control available.
