No pitch - just use screen, most people use tmux in exactly the same way - open a few splits and switch between them with keyboard shortcuts.

I switched from screen to tmux due to rumor about the screen code base. Maybe not a good reason. But I don’t regret it, tmux works well.

Just an honest opinion of someone who didn’t have skin in the game. Not sure if it helps.

The people GP are talking about don't know about GNU screen either.
