Delete Product IDs in Bulk
This feature would allow you to remove some IDs from your product database and thus lighten your database and improve your website's performance.
WHAT'S THE PROBLEM?
It´s impossible to delete IDs variations that include a deleted product attribute.
This happens when you delete one product attribute in a given point of time. Its product variations won´t be deleted. The feature "Orphaned variations" won´t help because the product still exists, but not the product attribute you have deleted.
This feature would look for all variations that include a product attribute that is no longer used by its product variation. Then, it would delete those variations.
