# ### [waybar-dev.sh](./waybar-dev.sh)
#
# Uses `entr` to watch for changes in my Waybar config files, and will restart
# Waybar on save. I use this when I develop themes and customization, you can
# pass `-d` to open a GTK debugger window as well, to get CSS selectors used
# for styling Waybar.
#
# Requirements:
