i3-nagbar is used by i3 to tell you about errors in your configuration file (for example). While these errors are logged to the logfile (if any), the past has proven that users are either not aware of their logfile or do not check it after modifying the configuration file.
i3-nagbar -m 'You have an error in your i3 config file!' \
-b 'edit config' 'i3-sensible-editor ~/.config/i3/config'
