Right now replies under replies are invisible. I know you tried to show all messages in a thread back before some of the display bugs were worked out, but I would still love to be able to see a full conversation just by scrolling. Maybe there could be a depth limit after which you’d need to hit an “expand all notes” link if it gets too messy, but at the moment a lot of replies just get buried if they’re not directly replying to the original post.
