Key points

• Lean methods can give rich insights: Even a few, short sessions with a handful of users can generate useful inputs for a user‐centric design process.
• Design for beginners: An interface that supports novices will also support experts.
• Keep it simple: Focus on functionality that supports core search and discovery tasks.
• Popular or high‐value features should have prime position and rarely used or low‐value features should be hidden or removed.
• Visual cues are important for usability, as is balancing the visual space.
