It would be a really good functionality that allows customers to see only items that are actually in stock, i.e. where the stock is “In stock” or “Get in stock”. Especially in those product groups where there are a lot of products, it would make it easy to get an overview and you have the opportunity not to have to deal with products that cannot be bought anyway.
I imagine that this function could be either as a check option under the item group text (top of the list view) or as a filtering option in the filters in the left menu.
