Add a smooth, customizable scroll-to-top button to your storefront. Control per-device sizing, offsets, and placement (RTL supported). Set button and hover colors, icon colors, and hover border width. Choose where it appears: desktop, mobile, home, product, collection, or other pages. Updates apply instantly after you save settings. No theme code editing required. It stays out of the way until shoppers need it, improving navigation on long product lists and blog posts.
