title: Tmux vs. iTerm2 split panes
body: <p>Why should I use tmux when iterm2 has split panes?  </p>
  
  <p>I have never used tmux, and want to know if there are advantages to using that in my workflow instead of the split pane features iterm2 has.</p>
  
  <p>I really like the dimming of inactive windows that iTerm2 split panes offers.  Does tmux do something similar?</p>
  
  <p>What are the advantages/disadvantages of each?</p>
