shortcode tab include draft products & variatopn products wrongly displayed

Hello friends, two issues, Just to let you know bc I could fix them by changing briefly your code:
1- the tab shortcode does not filter draft products, this is a problem bc you have to send to trash to avoid product is displayed. I could fixed adding the code: $args['post_status'] = 'publish';
before line539: return wc_get_products($args);, in wpc-utilities.php.

2.- Variable products without price changing wrongly displayed: ie: $20-00-$. I could fixed replacing the code in hook.php line 196 (inside conditional if (is_array($variation_price) && isset($variation_price['price'])) { code replaced }:

$first = array_shift($variation_price['price']);
$array_pop = array_pop($variation_price['price']);
$last = ( !empty( $array_pop ) ) ?  "-" . get_woocommerce_currency_symbol() . $array_pop : '';
$var_price = get_woocommerce_currency_symbol() . $first . $last ;

which prevents displaying the “-$” if array_pop($variation_price[‘price’]) is empty.

Now, I have to re-change after every update. It would be great if you could fix them for next versions.

great plugin many thanks friends
