Improved list designs. It's refreshing.

What you can’t do is create good experiences without knowing your content structure. What is your content made from, not what your content is.

It means:

We’d really like to understand the type and structure of the content for this project. Don’t worry, you don’t have to write anything yet, just help us understand.

Extending the atomic design with applications and principles:

Applications provide a place to document overall product and business information to give context about how and why the pages within an application are organized.

Infinite Scroll checklist

*If in doubt, always prefer pagination.

• With infinite scroll, always integrate a footer reveal.
• Consider separating “old” and “new” items visually.
• Provide an option to continue browsing later.
• Consider using “load more” + infinite scroll together.
• Consider using pagination + infinite scroll together.
• Change the URL as new items are loaded in and expose it to users.
• Allow users to jump to any page with a pagination drop-down.
• Consider using scrollbar range intervals.
• Consider allowing users to pin or bookmark items/areas of interest.
• Make sure accessibility and performance are major considerations in the implementation.
