If you want a little bit more of a batteries-included experience, Zellij[1] is to tmux what Fish is to Bash and what Helix/Neovim is to Vim. If you like any of those, I highly recommend giving Zellij a try.
I gave it a try earlier this year but because of some bad incompatibility with Codex I had to go back to tmux, and then I just never picked Zellij back up. I thought about giving it a shot, but now I'm reading about herdr here which seems pretty cool too.
