Just to show an example:
That's the URL generated from the New Posts page, which takes me to the first unread post in that thread.
When I click it, it's mapped to an absolute post...
Can you show the specific URLs and screen shots of what you are suggesting is happening below:
Because you've lost me now. None of the URLS or how they work or are interacted with change from XF1 to XF2 in the core software.
Sorry, but I beg to differ. XF1 appends an unread to the URL taking you to the latest post / message
The same happens in XF2, which is mapped to the unread post ID, and tagged to the end of the URL...
