Care to clarify "screen is voodoo. tmux isn't."? That's pretty meaningless.<p>The overall design to tmux is quite a bit cleaner, and (having poked around in their respective sources), I know which I'd be more likely to contribute patches to. It took screen <i>forever</i> to get vertical splits (are they still an unofficial patch?), whereas tmux already has dwm/XMonad-style layouts.<p>tmux is also included in the standard OpenBSD install. Make what of that you will.
