// Step 2 - Inject De-Pagify (https://github.com/ericclemmons/de-pagify/raw/master/bookmarklet.jquery.min.js)
// Step 3 - Run the following in the console:

jQuery('td > table:eq(1)').depagify('td.title:last a', {
    filter: 'tr',
    threshold: 'td.title:last a',
    effect: function() {
        jQuery(this).fadeIn();
    },
    events: {
        request: function() {
            jQuery('tr:last', this).remove();
        }
    }
});

// Step 4 - Now scroll down to the "More" link for content to automatically load!
