I would +1 this request. Very important to troubleshooting variant stock levels for us.

I'd like to see inventory history with the ability to change date ranges (1,7,30 days, custom date range, etc). This can show you how many items sold last month and how many you need to reorder for inventory.

Big time wanted.

That would be great if we could see some stats and stock levels during the year! + if we could add inventory cost
