• How RV bypass browser's maximum scroll limits?
• How RV supports dynamic item widths/heights? (CellMeasurer shadow rendering and size caching)
• How to properly tune sectionSize property in a Collection component? (how it works and why the need of section grouping)
• How RV compares with native browser scrolling (show some benchmarks and graphs)?
• How RV supports scroll-to-first (chat style) use case?

Other questions from my workmates

• Does RV support flexbox layout?
• What's the data model RV uses? (No data model, just a collection length and indexes)
