Very promising project that I hope it will take off and succeed. I recently switched to zsh with the addition of oh-my-zsh and I am happy how it has features like auto completion and command validation of some sort, but this could take it to the next level. I am just afraid to change to it and be disappointed about some incompatibility issues or bugs / crashes. I will observe and wait until it's quite popular to hop…
Try fish shell. It has auto completion by default and is easy to configure with web interface "fish_config", no need to rely on some community repo like oh-my-zsh. There can be bugs if you set it as default shell but i just append "fish" at the end of my .bashrc :)
I tried it ~7 years ago and thought it was severely lacking, so I just stuck with zsh and have never really had a reason to look back.
Maybe I'll check out fish again at some point - what features does it have that drew you to it?
