Probably related to the same change that brought the black bar, but the Chrome extension I use to add collapsible comment threads is now broken. Can we please get native collapsible threads here? edit: Also I just attempted to use an emoji for the first time here, and it was stripped. ???? edit2: I thought it was a simple design update, had no idea it was a tribute.
