Not complaining here, so please do not take it as that. I am a legacy Threads user, and it is still by far the best system out there.
But the new little arrow icons for jumping to the first unread post are in my opinion, cumbersome and not necessary! The previous system we had where you simply click the link to hit the first unread post is so much easier, and already my beta board testers really don't like the arrows.
It has been compared to other forum systems that do NOT jump to the first unread thread (I won't name the heathens)...as this is one of the features that to me distinguishes Threads from other forums.
Again, just an opinion from me. I just saw no reason to have to change that, and will be forced to implement the hack reverting back to 6.4 style links for my boards.
