As far as I know this isn’t a feature that exists, but I know the protocol should make it fairly easy.
What I’m thinking is for Lemmy to basically have the option to inherit the comment thread when posting a URL to another fediverse service.
E.g. If crossposting a Lemmy thread, you get a tickbox saying “inherit comment section” or something and it makes the new thread effectively a symlink to the original.
This could also be used to bootstrap other fediverse services like pixelfed and peertube by enabling people to comment directly from their Lemmy instance.
It’s been declined https://github.com/LemmyNet/lemmy/issues/4225
Making it a checkbox is an interesting idea though, but could still be confusing reading the comments with the different contexts.
This is true but the problem is seeing repeat threads on the front page. Maybe it is a stretch but would it be possible to stack the comments under each other separated by a head of which sub the comments are from
