The comment before, since it was basically a context checker. So for example, if there’s a long conversation in between two posters and someone interjected in between their posts, you could quickly check to see which comment was being replied to.

It’s a super useful feature for long comment threads. They’re not all that common on Lemmy, but we’re all hoping there’ll be enough activity to justify such a feature.

It’s one of the features I miss most from Apollo! It would preview the comment that’s a direct parent to the selected one. Great for the reading and comprehension experience across many use cases.
