Shopify is gradually rolling out a redesigned admin to all merchants, with new colors, type, and icons on every page and no setup required. The store picker, search, and notifications have moved out of the top bar and into a side navigation that merchants can collapse when they want more room. Sidekick now opens as a small chat window floating at the foot of each page and expands into a side panel for longer tasks, because Shopify says merchants increasingly use the assistant as their main way of working, with daily Sidekick sessions up 4.8x from 2025 to 2026. Admin UI extensions pick up the new styles automatically, but custom App Home interfaces built without Polaris web components stay on the old look until their developers migrate.
