vs-wal has some issues such as illegible text and no live reloading,
however, it is (from what I know) the easiest way to use a color scheme
consistent with your setup.
Code will use the default dark theme if vs-wal is not found.
The desktop directory is used for desktop-related things that may be
useful outside of bspwm (such as caps lock functioning as ctrl +
escape). Whether or not this is needed is questionable, but it is an
option for now.
It may be better to further split these directories and avoid the
generic word "desktop" altogether.
