    - [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
