I made a “storage_alert” mod that is not at all polished (maybe I’ll get around to it someday, or someone else is welcome to do so) that can alert you about items that are failing to restock.
If you decide to use it, the border of the window it makes is draggable (it should start off on the left edge of the screen; if the list is empty, it’ll be a small brown circle); you can also right-click the border to collapse or expand it in case it’s being big and annoying and you already know you can’t reach those items.
