-Describe specific features of your extension including screenshots of your extension in action. Image paths are relative to this README file.
+## Key Features
+The extension uses sophisticated optimization techniques to ensure smooth performance:
 
-For example if there is an image subfolder under your extension project workspace:
+- **Multi-level Caching**
+    - Workbook cache prevents redundant parsing of the same files
+    - Sheet HTML cache eliminates regeneration of previously viewed sheets
+- **Smart Loading Strategy**
+    - First sheet loads immediately for instant feedback
+    - Additional sheets load on-demand when selected
+    - Preserved webview context maintains your state even when hidden
+- **Responsive Interface**
+    - Immediate loading spinner provides visual feedback
+    - Sheet-switching indicators keep you informed
+    - Persistent state across view changes
