       - allows focusing on clients based on direction (up, down, left, right) instead of client
         order
 
+   - [focusfollowmouse](https://github.com/bakkeby/patches/wiki/focusfollowmouse)
+      - the window under the mouse cursor will receive focus when changing tags, closing windows or
+        moving client out of view (as opposed to the most recently focused client)
+
    - [focusmaster](https://dwm.suckless.org/patches/focusmaster/)
       - a simple patch that just puts focus back to the master client
