  - - For temperature type, use `temperature_type = "<kelvin|k|celsius|c|fahrenheit|f>"`.
  +- Note that if a flag and an option conflict, the flag has higher precedence (ex: if the `-c` and `temperature_type = kelvin` both exist, the Celsius temperature type is ultimately chosen).
  +- For temperature type, use `temperature_type = "kelvin|k|celsius|c|fahrenheit|f"`.
  +- For default widgets, use `default_widget = "cpu_default|memory_default|disk_default|temperature_default|network_default|process_default"`.
  Another use is to set colours, under the `[colors]`. The following labels are customizable with hex colour code strings:
