Feedback on meaningful sections of text (or meaningful feedback on short sections)

The feedback feature can only work with a short section of text without getting very confused and off topic. Because the sections offered for feedback are so short, they're out of context, meaning that most of the feedback is about what's lacking in that short sample of the text - fuller character or setting details, for example. It would be good if the feedback feature could either evaluate a full text properly, or limit itself to commenting in detail on the sample of text, with the understanding that it's taken out of context.
