[Update] Never mind, I've found it! In any list of Posts, if you click on the little icon in front of the thread title (with the tiny arrow pointing at a document), it will take you to the first unread post in that thread. Hovering over that little icon gives you a tooltip of something like "View first unread post". So the feature *does* exist. Am I the only one who hadn't found it?

[..] the "view first unread post" functionality

Regardless of how many posts per page your settings are, if the number of new posts spills out onto the second page before you've read them all on the first page, then the "view first unread post" will take you to the first post of the second page, instead of the first unread post still on the first page.

But I wonder now, if its because I've already opened the first page, instead of using this newly found link.

… works for me, been using it since I joined the forum.

Nope, not here. (I was quite tempted to edit out all the “you”s here )

I’d bet on this.
