Thanks for working on this it is a really useful addition! 🔥

I have made a couple of reactors to keep the feature as an opt-in util. Despite normal log levels and also box where formatting for them is optional, with tree, when reporters don't implement it (basic, json, browser, etc) it will lead to and unreadable output. I am thinking to introduce more of formatting utils like this consola/utils subpath so we can easily scale without worrying about this.
