Option to hide out of stock items in the store.

I have some products that goes to 'Out of Stock' very quickly. That products continues to show on 'Latest Products', 'Feature Products', and so on. I think that opencart should have an option (global) to hide all the 'Out of Stock' products, or an individually option (by product), to hide that product if it goes to 'Out of Stock'.

Thank you.

how about having the stock amount listed on the product page?

don't think there is currently an option to display that...?
