Thunder is great at displaying the number of comments for each displayed crosspost of the currently viewed post. This helps me find out where further discussions of the topic at hand are separately happening, as opposed to me poking through several crosspost links only to find out that there is nothing going on there.
Alternatively, seeing 0 comments can help me more quickly decide to go to those links to intentionally seed more activity among the crossposts (and help Lemmy's "bustling" appearance to would-be members and redditor converts), haha.
Regardless, it's always nice to see the comment count before tapping crosspost links.
Additionally, it would be great to press-hold on crosspost links and copy them without having to open them.
