And iTerm won't have a way to restore them, right? The `tmux resurrect` plugin can save and restore all your sessions, even after restarts. At the moment I have 45 tmux sessions running and I'm not worried in the slightest about not being able to pick up exactly where I was for every project.

Also, tmux is a nice way to "bury" your "windows." Hiding an iTerm window can only be done by covering something with it or minimizing it, but a tmux session can be detached from/attached to at will, and when you're detached it doesn't add cruft to your window management.
