VERY Well Done!

Works like a charm! Sure there are a number of bulk editots, they are all fine when you’re doing something simple.. editing a product’s title.. sku.. etc.
In my case, I needed something to add variations (with their own descriptions, images, etc) to ALREADY existing products.
I tried ALl Import (too dificult, not sure if it’s even possible).. I tried PW Bulk Edit (really good, but you have to pay, and still not the control and options that this plugin has!)
The binding feature is excellent! Ajax loading, no need for page refresh and filtering options!
