A couple weeks ago on an unrelated review, I remember a commenter asking if I could review a Linux distribution called Stella. It seemed interesting, but I didn't think much of it until the last few days when its release of version 6.3 made news on several major Linux news sites.
A lot of distributions that I come across that aim like Stella to be more user-friendly than their respective parent distributions are based on Ubuntu. There are quite a few based straight on Debian. There are also a handful based on Slackware, Arch, or Gentoo, which are all generally not very easy for new Linux users to use. And there are a few based on Fedora, though I feel like the only big-name one that's still around is Kororaa (and even that was originally based on Gentoo, so it hasn't been based on Fedora for that long — plus, Fuduntu forked from Fedora a while ago, while I haven't heard anything about Fusion recently). But until now, I don't think I've ever heard of a distribution that aims to make straight-up RHEL/CentOS more user-friendly.
