Smart Product Filter & Search

This app is amazing. It allows for much better customization than my default Shopify theme's filter. What's even better, however, is the customer service; I had some trouble integrating the app into my theme, so I sent them an email. Even though it was over the weekend, they quickly responded and resolved the issue before it was Monday. I even asked them for help integrating another app of theirs within the same email thread, which was annoying of me, and yet they were still kind and resolved the issue quickly. Definitely give it a try, I highly recommend it :)
