Example where I would have needed this a while ago:

After almost every reboot on my laptop I start a tmux with a certain layout with some semi-long-running processes which I want active and not daemonized, I can also not start them at the same time. I start them in a tmux with the layout split into 4 quadrants, then create a single new window so I don't see them all the time and can work there.

Took me at least 2h to figure that out, how to split it programmatically and start everything in the correct "corner". Now it's just running a script and not having to anything manually.

This would have probably saved me 2h. And I have totally forgotten everything again now, so much for "just a ctrl-b" away. (Using tmux daily, but not in THIS way)
