[request] Collapse conversation by clicking outside of it

This was a Qvitter feature that I dearly miss. Currently if you expand a post to see the whole thread the only way to undo that is to scroll to the top and hit the collapse button. Sometimes the post you clicked on to expand isn't even near the top and it's not pleasant. It would be nice if I could just click outside of my timeline - perhaps on the background area to just automatically close any open conversations. Alternatively the posts in the conversation could just have a minus button where the plus button would normally be when they aren't expanded and I could just click that.

I didn't see any open issues for this, sorry if it's somehow a duplicate.
