Would be nice if Premium LinkedIn did not include too much irrelevant content. I only care about relevant content.

remove-linkedin-irrelevant-content.js

(function() {
    function removeNonsense() {
        if ( !document.head || document.querySelector("#remove-useless-stuff") ) {
            return;
        }
        var style = document.createElement("style");
        style.setAttribute("id", "remove-useless-stuff");
        var text = "#today-news-wrapper, #cspad, #csp-ad, #jobsForYou, .linkedin-recommend-job, #ad-slot-4 { display: none !important; height:0px !important; opacity:0 !important; visibility:hidden !important; }";
        style.appendChild(document.createTextNode(text));
        document.head.appendChild(style);
    }
    removeNonsense();
})();
