I think I remember seeing it on this community. It was a darkly colored video. It was mostly focused on UX design, and the guy was talking about pretty innovative features with auto completion suggestions and undoing and things like that. Does anyone remember it or have a link? My search was fruitless.
Yes, performance of zsh. Idk if it’s a bug, a language issue or just a downside of having more features but it is slower than bash
It’s not because of features, since fish has tons of stuff as well and is super snappy. Someone pointed out most of those extra features are implemented in zsh itself, rather than in C, like core features.
