would be possible to add "View new posts" in the header, near the "View your posts"?

Unless I do something terribly wrong the "view new posts" is only on the homepage.

Have you tried the spy? http://deskthority.net/spy.php

should I use that instead of new posts?

You can. It's up to you.

okay I tried to use it. It works but it's not exactly the same thing.

- you get a list even if there are not new posts, while the new posts listing gives you an exact view of what you have to read
- it lists each post and not each thread

anyway it's a very small thing, nice to have but not really that important
