Show content of posts on the saved posts.

You can already do that. In your themes’ functions.php file, simply add something like this:

function twentyseventeen_save_for_later_html( $html ) {
	$html = '';
	if ( has_post_thumbnail() ) {
		$thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id(), 'thumbnail' );
		$html .= '<div class="rs-item-image" style="background-image: url(' . $thumbnail[0] . ');"></div>';
	}
	$html .= '<div class="rs-item-float">';
		$html .= '<div class="rs-item-title">' . get_the_title() . '</div>';
		$html .= '<div class="rs-item-date">' . get_the_date() . '</div>';
	$html .= '</div>';
	$html .= '<div class="rs-item-content" style="float: left; width: 100%; margin-top: 20px;">' . apply_filters( 'the_content', get_the_content() ) . '</div>';

	return $html;
}
add_filter( 'rs_saved_for_later_item_html', 'twentyseventeen_save_for_later_html', 10, 1 );

I’ve used get_the_contents() – you can use get_the_excerpt() without that apply_filters call, so:

$html .= '<div class="rs-item-content" style="float: left; width: 100%; margin-top: 20px;">' . get_the_excerpt() . '</div>';

Of course, some additional styling may be required.

ok i can’t try it because the plugin doesnt work correctly anymore. I cant save anymore.
