Bring back the mark all posts read option on the main forum page.It is available under your login dropdown, under unread topics or updated posts. I guess looking around for things and readjusting is the price of a cleaner layout. Slightly more annoying to me is not being able to see, immediately on the left margin, which subforums have new posts, in the mobile view (it's still there on the desktop.) But it is much more manageable on mobile devices, so fair enough. Just check for unread topics in the login dropdown.
Not convenient. So now I have to click the drop down... then click another link... then click another to mark them all read. Just put the mark all posts read
back. One click and done.
