One feature that is missing that I like to use is curly brace expansion to produce multiple arguments. For example,

$ mv *.{jpg,jpeg}

Maybe this will work for expansion: https://github.com/nushell/nu_scripts/blob/main/modules/filesystem/expand.nu

It's in the "filesystem" section, but I think it works on any string, not only paths. See the ugly duck example. I didn't try it myself yet.

BTW the nu_scripts goodies are available in Nixpkgs, so since you are using Home Manager, it's easy to integrate. Take a look at my config for starters: https://gitlab.com/tad-lispy/nixos-configuration/-/blob/bb614ae3639a504912db167f5bd7e6651d28f604/tad.nix#L39-47
