Handling "more comments..." pages

[insin]

HN comment threads kind of fall apart once they have more than a few hundred comments and they get split into separate pages - this also breaks our highlighting of new comments as we count viewing the first page as your most recent "visit" to the entire item thread.

What should we do about this?

• Reset to the last "visit" if you click the "more comments..." link so new comments get highlighted appropriately?
• Auto-load the complete thread then apply highlighting?
• Provide a link to react-hn with last visit details, which will let you read the entire thread in one place?
