I've usually been against auto-formatting on save and instead preferred
to trigger it manually using its own keybinding.
I'm enabling it for now to see how I feel about it and I'll either keep
or revert it.
Whilst I wasn't able to get it to work for all my use cases previously,
it is useful for creating alternative files in Fractal, such as
switching between the `*.config.yml` and `*.twig` files for a component.
Other use cases, such as creating alternative files for classes and
tests in PHP and Drupal projects, I can look at again now the plugin is
installed.
