 2. **Feature Highlights**  
    - Besides basic WM functionality, maomao provides:
-     - Smooth and customizable animations
-     - Excellent input method support
-     - Flexible window layouts with easy switching
-     - Rich window states: swallow, minimize, maximize, unglobal, global, fakefullscreen, overlay...
+     - Base tag not workspace(supports separate window layouts for each tag)
+     - Smooth and customizable complete animations(window open/move/close, tag enter/leave)
+     - Excellent input method support(text input v2/v3)
+     - Flexible window layouts with easy switching(scroller,master,monocle,spiral..etc)
+     - Rich window states(swallow, minimize, maximize, unglobal, global, fakefullscreen, overlay...etc)
      - Simple yet powerful external configuration

-3. **Philosophy**  
-   - *Maomao* has no rigid design ideology—you could call it an eclectic hybrid of various compositors.
+     - Sway like scratchpad and named scratchpad
+     - Minimize window to scratchpad
+     - Hycov like overview
