I've been wondering the same thing. Also, for me in both Firefox and Opera, some (but not all) of the boxes at the left side of every thread in the list are missing. Those are the boxes that show whether a thread has been read, updated, pinned, etc.
Many thanks Publius.
I was wondering if it was just me though I did see a thread further down the page about losing the info re numbers of visits.
I've tried with opera, google chrome and vivaldi and got the same view from all three so I guess it's been removed for the moment though that seems very unnecessary.
