Low priority:
Regarding the "What's new" page. Currently (I'm in desktop Chrome), when I click on a bolded thread (bolded indicating new posts), read the new posts, then hit (back button, alt-left arrow, etc.) to navigate back to the "What's new" page, the thread I just read is still bolded. I have to reload the "What's new" page again in order to get the "read" thread to unbold.
On the old site, when I hit the back button, the thread(s) I had just read through was unbolded (indicating no new posts). It helped to be able to quickly see the threads I had read.
I hope this is clear. Many thanks for your work clashmore. Again, this is a low priority (I'm just lazy).
