Being able to sort the novels by the rating of 'the good readers' would be nice. Maybe, just maybe, you don't trust any reader who rated 《Invisible Dragon》 anything other than a 1. You might not require them to sully their self by actually voting a 1 because it would require them to be at the Invisible Dragon page. Maybe you don't trust any reader who neither has 《I Shall Seal The Heavens》 on their reading list nor has rated it any lower than 4. (They could have rated it well without it being on their reading list.) Maybe it isn't enough for them to have it on their reading list because it might be on an ignore list. If this feature existed, I would sort novels by the rating of readers who rated 《Youjo Senki》 at least 4. Disclaimer: 《Invisible Dragon》 isn't so bad. Some people just think it is.
