I really enjoy #powershell in many ways. Its #objectpipelies are powerful and expressive, it seamlessly interfaces with a plethora of platform APIs, and its syntax is discoverable with incredibly rich tab completion and help on the command line or web.
I would love to find some way to bring these concepts to *nix for folks who might not be able or willing to switch to specialized shells like #nushell or #elvish. Both projects are amazing but I honestly can't afford the time to rewrite the rich functionality I get from zsh /oh my zsh/plugins.
Maybe when I retire :) Come to think of it, building similar functionality in nushell/elvish to what I have now would be a delightful rabbit hole to dive down. I think I shall put it in my "Shower Ideas" @obsidian note for future inspiration :)
(For example, the #tmux plugin in oh my zsh has a setting to ensure that only one instance of tmux runs no matter how many shells I open.)
