When viewing product details for a composite product, if you go to the tab called "composition" where it shows all the child SKU's that make up that composite product, it currently shows a column for the quantity but it doesn't show the current stock level of that child SKU.
If you have a number of child SKU's that make up a composite product and then one of those child SKU's go out of stock, it will then correctly make that composite product out of stock too. It then becomes a very time-consuming job to search through each of the child SKU's to find which is causing the parent to go out of stock.
On a composite product 'product details' view, when you go to the 'composition' tab, please can you add a column after 'Quantity' called 'Stock Available'. This new column would show the current stock availability for that child SKU, thereby allowing a user to very quickly see which child SKU's are getting low or are currently causing 'out of stock'.
