Swedish is on the "no" branch of those letters

...and all I hear is: "this stuff isn't ready yet" and "I'm going to be starring at Unicode glyphs the next time I have to tinker outside of my GUI".
This really isn't a zsh problem, but a "people putting too much stuff in a 'getting started' config".
I used zsh for 15 years before looking at any plug-in manager, you can get a lot of the good stuff like the completion by just going through the first-run wizard included in zsh. A lot of stuff is included directly with zsh, including various prompt themes (which is what that tutorial wants extra fonts for, because they use a fancy prompt with custom glyphs; I don't think any of the built-in ones need that)
Things like fuzzy history search with fzf is usually included with fzf's distro package and the additional zsh-completions package for less used or newer commands is also packaged by most distros. In my experience, a lot of the other plugins are stuff that could be a standalone script instead of a plug-in anyway.
I don't think working overtime has much to do with WFH vs office for most people. We have a lot more WFH here since covid, and the only people I know that work a lot of overtime already did that before WFH was introduced.
For me, WFH means an hour more of free time, as I don't have to spend it in traffic on my way from and to work.
