Just wondering - how are you meant to sort the order of associated products? It seems that they are sorted by their "ID", from smallest to largest.
If you forget to add an associated product, for example an XS Variant, and then add it - this will appear at the end, after the XXL etc. Or if you add a US8 after you've already added US10, it will be in the order US9, US10, US8 etc
Any ideas? There isn't an ordering column that is obvious.
