Interaction Design

This one helps you design interactions that feel responsive and intentional rather than arbitrary. You'll use it when you're building animations, transitions, microinteractions, loading states, or any touch-based patterns like swipe and pinch-to-zoom. It includes reference guides on animation timing, error feedback, and accessibility considerations. The best practices are solid reminders: keep animations under 400ms, respect motion preferences, and always provide keyboard alternatives. Honestly, the interaction pattern reference table alone is worth having around when you're debating whether a double-tap or long-press makes more sense for your use case.
