Ooo, this is very nice and a huge improvement 👌 🎉
Two things:

1. I think that the contrast between the light theme of the website and the dark of the terminal output is a bit harsh. My preference would be to have a lighter theme for the terminal as well, but I guess you and @lwjohnst86 decided on this theme in Soil?
2. In the output below, can we show the files inside the resources/ folder as well?

Thank you! 😊

1. I don't think we decided anything formally. I made a case in docs: 💄 beautify CLI output in docs check-datapackage#342 for that the default light/white background in the second screenshot there makes it hard to distinguish where the output starts and ends from the rest of the text.

   I also thought it would be nice to have some indication of what is output from a CLI command versus from Python code, but it is technically not necessary. We could still achieve that with the use of other dark colors too of course, I just modeled this of the colors that flower use in the terminal so that the docs look the same as the local experience (not necessary), which in turn are modeled after what I arbitrarily think looks good in the terminal =) We can totally change it, but maybe that happens in a follow up PR that since it might be a bigger change that also involves changes the default flower colors in terminal and the cdp docs?

2. Yup, totally! Here or in a follow up PR after your change in feat: ✨ add file_tree() seedcase-soil#39 that adds the file tree viewer?
