Look into “Oh My Zsh” or similar plugin managers. OMZ is bloated as fuuuck and you’ll probably want to replace it with your own custom configs at some point, but it’s the easiest way to see what a decked out zsh feels like. It’s a good starting point for sure.

Personally I’m down to just 4 plugins with minor config tweaks on top of a bare zsh install. I’ve read good things about Starship but I’m happy with my current setup.

Now that you’ve set zsh as default … switch to fish

Stallman report is a bs that tries to undermine the concepts of free software and all. I think it was drew devault that did this trying to take over fsf or something(more details here). All the quoted stuff are majorly misleading, and stallman being autistic-programmer guy who is not in a position of talking much about sex, said and asked some controvertial stuff that a teen would make trying to think what is right and wrong. His lack of knowledge of anything other than software made him say some statements for which he apologised later on. And all this guy did with stallman report was bringing all old accusations and framing it in a way that would make him get control of FSF and (very likely)make free software serve corpo greeds(say by removing copyleft stuff from gplv4 which is applicable for all v3+ software)
