I always setup my terminals to open a tmux session by default (or attach to any existing one). For example, in my ~/.config/alacritty/alacritty.toml:

    [terminal.shell]
    args = ["-l", "-c", "tmux attach || tmux"]
    program = "/opt/homebrew/bin/zsh"

tmux supports tabs so you can have multiple Claude Code sessions running concurrently. You do need to learn a few tmux keyboard shortcuts to use it effectively (e.g. opening/closing/switching tab).
