Globo Product Options, Variant

I do like this app... it covers all of the variations you can think of and helps optimize revenue. I only wish it would WARN YOU if you have already added a variation to a product. I have messed up several of my listings (and lost money!!) because I switched variations thinking it didn't have one set up - but it already had a variation profile (that was different). PLEASE PLEASE add a warning in the future! That would be so helpful...then it is 5 stars!!
