Meant primarily for long threads (35+ comments)

Mainly because sometimes we just want to get to the reply box after reading through a long comment section and checking several times over now that highlighting new comments is a default feature and the fastest way to do that is closing a bunch of threads or tapping the screen a few times/scrolling.

Admittedly it's kinda silly but being able to collapse all the threads and get straight to the reply box seems like a pretty good QoL feature.

I think it'd be useful to merge duplicate threads when there's two topics that are very close to each other. I don't want the stackExchange style "closed as duplicate of x," but I think it would be worthwhile to simply have the comments moved to the oldest thread and transfer any votes that are different users on each topic.

This way, we aren't losing discussion by flat-out deleting topics that are dupes, and we're also able to take some sort of action on threads that are dupes.

Just a thought.
