Tira here, from Shopify Support.
Thank you for reaching out, great question! I understand how a thin scrollbar can be non-ideal for your theme. I want to mention that this is a change that could be made on your theme by our design team (as it is a free theme from Shopify), however it is not guaranteed. This is because typically the scrollbar size is determined by the browser that the viewer of the store is using, and if any changes are made, it's possible they could be inconsistent on many devices, so we do not recommend making this change. It is important that your theme is consistent on all devices that customers use, so that they have the best experience of navigating your store.
Each store on Shopify comes with 60 minutes of free design time for themes designed by Shopify. You can use to make certain modifications to your theme based on our design policy. You can view our policy here.
Let me know if that helps!
