HRIDZ review for Essent Preorder Back in Stock

Great App. Only missing features I would think would be are.. 1) preorder label on the product and colelction page for releavnt products 2) other one is email customization for preorder product orders 3) Preorder message and shipping time customizations for preorder product checkout page. 4) on product page, when customer try to add more qty then set limit of allowed preorder quantity, it doesn't show any error or notification message that qty limit reached or something. 5) Preorder available quantity bar can ber useful on product page.
