This vQmod extension adds visual improvement to OC shop when products are Out Of Stock. Additionally extension adds visual effect with Pre-Order functionality when product count is negative or even disables "Add to Cart" Button with replaced text to "Out Of Stock".

Visual improvement is by adding ribbons to product thumbnail and manipulating "Add to Cart" button:

• when product is Out Of Stock then grey ribbon is added to product thumbnail and "Add to Cart" button is removed at all. This allows easy to see which products are not in stock and disables to add it to shopping Cart.
  
• When product has negative value and administrator has enabled "Stock checkout" option in shop settings then orange ribbon is added to product thumbnail. "Add to cart" buttons works as usual.
