Just thanking all who have worked on this. We can not upgrade without SBA: From Tom who uses it most: "There are three things I like about the New Stock By Attributes:

The list is sorted by model number, rather than product name. This helps as we update inventory. We use the model number to find items in the admin.

The list is searchable by model number. This helps us because we have so many items that are stocked by attributes.

We used to use a link to Stock By Attributes from the individual product admin page to go quickly to the attributes for a product. While this feature is now gone, the two features above make up for that. It would be nice to reestablish that link or make a tiny statement or icon next to the Products Quantity to help us know if the product has attributes or not. That “A” Icon is displayed on an admin product page that shows all the products in a category or in a search of the admin.

And there is now a link to Stock By Attributes from the Attributes Controller page. At least I think that is a new feature. That can come in handy when working with the option names and values and then jump right to Stock By Attributes to finish the product info."
