Install Creates "app.css"

[morinap]

Running a mix tailwind.install as part of my normal build process on my development environment automatically creates a file at /assets/css/app.css. My project uses DartSass and has an app.scss file instead, so the net effect is that if I run my build from a clean working copy, I end up with an untracked file in git for app.css.

I propose adding a --skip-prepare option to the tailwind install task that will skip the modifications it makes to app.css and app.js if the user desires and have prepared a Pull Request for this functionality.
