+### Description

+Implements `swaymsg create_output` command, it allows you to create virtual/headless outputs. But in combination with a VNC server (for example wayvnc), this allows you to essentially have additional monitors, by connecting to the VNC server with an appropiate client (for example on an tablet or laptop).

+

+If you plan to use wayvnc, you'll need [virtual-pointer](https://codeberg.org/dwl/dwl-patches/wiki/virtual-pointer.-) patch as well
