Shopify Search & Discovery

Veru good app but the Shopify support is not on par with the rest of the apps on from the app store.
App devs are helping with app installation and customization but Shopify help is redirecting to public resources. Well, we won't need support if we could find our answers in public resources.
There is not even a support email where we can answer questions!

My question: how we can make the filters sticky on the default Shopify Dawn theme.
