 ## 2024-04-13 - Missing React.memo for FlatList Items
 **Learning:** The React Native FlatList components in this codebase frequently render unmemoized inline items (like `ContactRow`, `PasswordRow`, etc.), causing unnecessary re-renders of the entire list when individual state changes.
 **Action:** Always wrap long list item components in `React.memo()` to prevent cascading re-renders and improve FlatList scrolling performance.
+## 2026-04-17 - FlatList Missing Optimization
+**Learning:** The project is missing 'initialNumToRender', 'windowSize', 'maxToRenderPerBatch', and 'removeClippedSubviews' attributes for `FlatList` components.
+**Action:** Add these attributes to optimize list rendering.
