Thanks, I prefer the "What's New" as it shows the latest, but not all, but that is OK.
I'm confused! You asked for a list of the 25 most recent threads.
The "Latest Posts" section of the "What's New" page is a list of the 10 most recent threads, including both read and unread.
The first page of "New Posts" is a list of the 25 most recent threads. The default is unread, but you can change that to include both read and unread.
On my screen, the first 10 items on "New Posts" are exactly the same as "What's New", so I'm not understanding what you see as the difference between these two lists other than New Posts has 25 items on it instead of 10.
