Creating a new blog look

Hi there

watching this video, I decided to re-create my custom blog design - inside the new generatepress.

But:

1. How can I create a featured post, on top on all blog posts (on the blog page) (see link)

2. Is there a way for making the filters, and filter on category or tags? (see link)

(please notice the filter uses # and not ? in the url - this is for seo reasons)

3. is there a way to add reading time to the blogpost, shown on the blog page?

I have this code, but I don't know how to activate it on the posts on the blogpage.

function tu_estimated_reading_time() {
    $post = get_post();
    $content = $post->post_content;
    $wpm = 300; // How many words per minute.

    $clean_content = strip_shortcodes( $content );
    $clean_content = strip_tags( $clean_content );
    $word_count = str_word_count( $clean_content );
    $time = ceil( $word_count / $wpm );
    
    if ($time == 1) {
        return $time . ' minute';
    } else {
        return $time . ' minutes';
    }
}

add_action( 'generate_before_entry_title', function() {
    echo tu_estimated_reading_time();
} );
