Hey rj,
Glad you're enjoying Yotpo!
Sorry I can't help you with the CSV issue you're having, but have you seen our new On-Site Widget? The design is a lot sleeker/cleaner and there are more customization options. (Also, the default icon isn't a little dude, which I totally get would look funny on your jewelry store!)
kitbox.co, another Shopify store, is a good example of a store I think has done a great job with customization: http://kitbox.co/collections/inov8-weightlifting-shoes/products/inov8-fastlift-315-grape-atlantis
Thanks for the kind words about our system, even if you don't like our looks--it's what's on the inside that counts : )
