It’s pretty much exactly what you’re looking for if you want bash scripting with fish features and plugin extensibility.
The downside is you gotta take some time to set up your .zhrc and choose if you want to use a backend like oh-my-zsh.
I think the reason its on MIT license was because it was essentially just a bunch of scripts bundled together and maintained by a wide variety of people with no intention of making it the default shell like fish or bash is.









This looks like it was made to justify those insane text editors with “GPU acceleration” as if text editing requires interop with Vulkan.
