When adding free products it give that pop up box with a product listing.
For some reason, the product options are greyed out, it only selects the default options. Why is that? It’s not changeable.
Also, if someone clicks on the product from there, it loads it in that window and can be rather confusing getting back to the listing. Perhaps being able to add the product from the product page and/or a button next to “Add products:” at the top that says “Go Back to listing selection”
