With Hugo, all the files needed to modify the external look of the site are inside the theme folder. That's a bit different with Jekyll. About the URL: I didn’t know that, thanks. When I installed Jekyll, it was already set up with this URL scheme. Same for Hugo, it’s fhe default behavior, but it has a better scheme by default. As a noob, I didn’t check this when I started with Jekyll years ago. Maybe the devs should change the default scheme. But the issue with the URL scheme isn't the date, it's that if you change the category of a post in Jekyll, it changes in the old posts too. And I don't understand if you can omit the category, all the examples in the documentation include it.
