hi, congratulations for the plug-in, the best around!
I want to suggest this integration!
The inventory management of variable products (for example products with the variable SIZE), for the PLUS add-on (name and number).
When I add new, and choose a new size, the new size must be scaled from the inventory.
Moreover, if I have other views (front, back, side, etc..), with customizable levels (texts or images, etc..) their price must be multiplied by the t-shirt, added with PLUS.
