Google Chrome's recent update on handling notifications provides valuable lessons in UX design, particularly for in-product experiences. The changes include adapting defaults to the best specific case, offering one-time UX to help users learn new patterns, and avoiding interrupting user flows by using self-serve UI. These principles can be applied to improve user experience with notifications and other in-product experiences, such as onboarding flows, product tours/walkthroughs, in-app guides, feature announcement modals, etc. By following these best practices, designers, PMs, and PMMs can establish a positive relationship between users and the "in-product channel."
