Instruct: Classify Amazon reviews into positive or negative sentiment

I didn't like it because it will not allow you to bookmark a page so that you can continue where you left off. Plus it will not allow you to highlight anything so that you can go back and review it later. It's pointless to read anything because of the two reasons mentioned earlier. This is the earlier version. From what I understand the later version will let you do these two things.
