    - [ewmhtags](https://dwm.suckless.org/patches/ewmhtags/)
       - adds EWMH support for \_NET_NUMBER_OF_DESKTOPS, \_NET_CURRENT_DESKTOP, \_NET_DESKTOP_NAMES and \_NET_DESKTOP_VIEWPORT, which allows for compatibility with other bars and programs that request workspace information, e.g. polybar's xworkspaces module
 
+   - [extrabar](https://dwm.suckless.org/patches/extrabar/)
+      - enables an extra status bar in dwm in a similar manner to the dualstatus patch
+      - if the primary status is at the top via topbar then the extra status bar will be placed at the bottom and vice versa
+
    - [fakefullscreen](https://dwm.suckless.org/patches/fakefullscreen/)
       - only allow clients to "fullscreen" into the space currently given to them
       - as an example, this will allow you to view a fullscreen video in your browser on one half of the screen, while having the other half available for other tasks
