I tried it and it seems indeed faster than autojumper on my Macbook Air with bash. However, visually I don't see any difference, probably because other tools run on cd'ing to the next folder (probably git).

Also when I do `z doc` I expect to go to `~/Documents` like in autojumper, but in z.lua it jumps to a subfolder `~/Documents/projects`, which is annoying. Finally it does not seem to cycle through all matches when I repeatedly do `z proj` -- I like that about autojumper.
