Hey, the little house icon is basically a stylized rendering of a roof line, which comes from early pictographs of dwellings; it’s basically a memory cue. The arrow usually mirrors a real arrow from antiquity, pointing left for back, right for forward, and our brains quickly map that to navigation. From a UX perspective, users feel immediate familiarity; that familiarity reduces cognitive load and makes the app feel intuitive. But if you throw in a weird, overly ornate icon, it throws off that mythic shorthand and can cause users to hesitate. In the end, the mythic shape helps us get in the app faster, but we’re always balancing aesthetics with function.
