- Document performance issues in long sessions (scrolling lag, input jitter) - Create prototype implementations for virtualized message rendering - Add performance monitoring hooks for debugging render bottlenecks - Implement proof-of-concept with fixed-window message display Key approaches: - MessageLine memoization with custom comparison - Virtualized list rendering (only visible messages in DOM) - Scroll performance tracking with throttling - Stable scrollbar gutter to prevent layout shifts
