Redesigns create a peculiar onboarding problem: the user already knows how to use your product, but not this version of it. Sending a welcome tour feels patronizing. Doing nothing leaves them confused. Slack addresses this on the redesigned Activity feed with a compact three-step tooltip tour that fires on first visit. Each tooltip parks next to the exact UI element it describes, covers one feature in two sentences, then moves on. The sequence ends with “Got it” rather than “Next,” a small signal that the orientation is complete and the user is ready to explore on their own.
