Just getting started with zsh. Here's my current ~/.zshrc file.

.zshrc

ZSH=$HOME/.oh-my-zsh

plugins=(git node npm osx vi-mode)

source $ZSH/oh-my-zsh.sh

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" 
[[ -s "$HOME/nvm/nvm.sh" ]] && source "$HOME/nvm/nvm.sh"

# Use vi bindings in the terminal
bindkey -v

# Fix backspace action
bindkey "^?" backward-delete-char

# Use Vim-style indicators in the terminal
function zle-line-init zle-keymap-select {
    RPS1="${${KEYMAP/vicmd/-- NORMAL --}/(main|viins)/-- INSERT --}"
    RPS2=$RPS1
    zle reset-prompt
}
zle -N zle-line-init
zle -N zle-keymap-select

# Make vi mode transitions faster
KEYTIMEOUT=1

PROMPT="%{$fg_bold[green]%}» %{$reset_color%}"

alias ls='ls -GFph'
alias vim='/Applications/MacVim.app/Contents/MacOS/Vim'

export CLICOLOR=1
export LSCOLORS=gxBxhxDxfxhxhxhxhxcxcx
export EDITOR=vim

Doesn't your PROMPT kill anything nifty your plugins like git are trying to add? I ended up choosing the agnoster theme, but commenting out the context call from the bottom to eliminate the longish "user@host" part. Will probably be trouble if I update..
