Thanks, John, for confirming that this feature isn’t available yet.
We are not creating products with repeater fields. We use repeater fields to sort the display-order (list-order) of already existing products in category pages (we need more features than WP can do in this respect).
Sorting repeater fields with drag and drop works very nicely. We only need a (far) more compact display mode for product categories with hundreds of products. A grid, as linked in my initial post, would work best.
