Shopify merchants/experts - I need your advice

Hey all, I am building a Shopify integration for my company Log Harvestor. The integration will allow you to build custom dashboards using your Shopify Store's data. My business partner and I are trying to interview as many of you as we can to see what analytics are important you, and any pain-points/issues you may have had on Shopify. The phone call will be super quick - 15-20 min, or if you prefer i can just email you the questionnaire. Thanks!
