I recommend Byobu. Byobu is an elegant enhancement of tmux or Gnu Screen.
For me Byobu is for far easier to use than Tmux.

If you already are familiar with tmux, I don't think Byobu will get you anything (based on what I saw of the video).
It inherits and maps Ctrl-a, and makes the transition to using some of the nice new features available in tmux much more accessible.
