Pick any popular colorscheme, like dracula or catppuccin, get some good wallpapers and make a screenshot with your most-used (or just favourite) applications. Keep it simple

Thanks, LOVE is great!

I wish I will one day use on a real hardware!

Yep, although there’s no themes like with gtk and qt, you choose colors manually.

Doesn’t Debian Sid count as a rolling Debian?

Basically, nowadays Unix (or more formal POSIX) is a standard for operating systems to follow. Most modern operating systems are either derived from Unix (modern MacOS and Solaris), inspired by it (Linux and open-source BSDs) or at least POSIX-compatible (Haiku). Windows is neither of this - being monopoly they basically don’t need to follow a standard when they can force everyone to implement their solution.

So yeah, Unix is an OS and Windows doesn’t count.
