This is regarding the new forum design, but I can't find the thread for that...
The notification icon for new and unread posts seems to have gone missing. Iirc, it used to have a white 'bell' icon, as well as the little red square, but that doesn't appear anymore, and the red square disappears as soon as the first new post is clicked on, which means that for every subsequent post, I'm clicking on nothing... just the black background where I know the button should be.
I much preferred the old button, which became active just by hovering over it, so having to click on it was already a retrograde step, but this latest change just has to be a mistake, doesn't it? The fact that I haven't been able to find anyone else complaining about it makes me think that not everyone is seeing the same thing, but I'm getting it in both the 'Paradox' and 'Classic' skins.
