This looks extremely interesting! Is anyone using it as a daily driver on Linux? How has your experience been?
It's VERY refreshing, but I still have issues with it not short-circuiting when an error is thrown in a loop... Which I suspect will get fixed in time...
Returned back (from zsh) to fish this year and am super happy. Still the best built-in completion / history auto-suggest that I've seen in any shell so far, and super-fast at that.
Most importantly, barely any config needed (no needs for oh-my-zsh, prezto and all of those).
