I agree with the oh-my-zsh, but why specifically the fish theme?

From what I can gather it only alters the look (https://github.com/robbyrussell/oh-my-zsh/blob/master/themes...)

Hmm, does it? I installed it right away and it's pretty much exactly like fish (history traversal with arrows, case-insensitive matching, etc). I might be mistaken and it might just be omz.
