The "Generate more" button is currently not very useful at all, because it does not usually continue an incomplete sentence, and usually it is just like a new reply appended to the old one, which makes the feature pointless, since "respond again" does the same thing, but better. Fixing this to work as if it was AI Dungeon story mode/NovelAI and let it continue the sentence would make it a very useful feature, and especially since it would go a long way in fixing incomplete replies, which is one of the problems brought up the most often. I've decided that "bug reports" is the more appropriate section for this issue than "feature requests" though, simply because as it stands, "generate more" is borderline useless because of that issue.
