I like auto-complete in web-browsers, but I can't see a single use for it in my terminals.
After all, what Linux-user hasn't automated their terminal input to some degree? Nah, I'll stick with my [TAB]...
I tried it for a while and I just can't work with it. I'm back to fish 1.23 for now, and I don't know what I'll do when that becomes unmaintainable. I might just have some personal patches, I really wish they included an option to disable it.
