We could use a smarty linter/fixer to enforce consistency through all themes and modules: remove useless />, tags' attributes inline or one per row, etc. But honestly I don't know anything useful for that. I use VSCode and Smarty extension as a formatter, but it's still not perfect.

Yeah, I did try to find one years ago but unfortunately, it doesn't seem to exist at all 😢
