The New Posts uses read tracking to determine which threads to show, but doesn't update upon reload of the page. Those results are cached as they are an individual search. If you need new results, you'll have to click the link again to perform a new fetch of posts.
Recent Posts doesn't use read tracking (it is the link provided to guests) to determine what posts to show in the listing. As with New Posts, it requires a click of the link to function and not a simple refresh.
@PyroM yes, it is important
but if you do not know how each search works it is confusing
in addition both searches are for all posts in the forum, yet they are put in different places
adding to that, Recent posts show only when I click New posts so it is even more confusing for common user
That's why I plan to put that link in the navigation bar, close to "New Posts". The people will understand, when the links stand together. Thank you Brogan, your words in the resource describe it perfectly! My users an me feel as if we were blind without "Recent Posts", only with "New Posts".
Is there a way that I can use the find_new_posts for the "Recent Posts" functionality only? Because I am using it as a widget template, but it doesn't show anything... If I click on "Recent Posts" however, I am getting the posts. What am I doing wrong?
