Always start tmux with this (~/.zshrc )

if command -v tmux &> /dev/null && [ -n "$PS1" ] && [[ ! "$TERM" =~ screen ]] && [[ ! "$TERM" =~ tmux ]] && [ -z "$TMUX" ] && [[ "$TERM_PROGRAM" != "vscode" ]]; then
  # Get the first unattached session, if any
  first_unattached_session=$(tmux ls -F '#{session_attached} #{session_name}' 2> /dev/null | grep ^0 -m 1 | cut -c3-)

  # If there's one unattached session, attach that one.
  # If not, just start a new one.
  if [ -n "$first_unattached_session" ]; then
    exec tmux attach -t $first_unattached_session
  else
    exec tmux
  fi
fi

You can open a new terminal without tmux by executing:

gnome-terminal

This will create a new window but it will have TERM_PROGRAM set to tmux, so tmux won't load (due to the condition).

TODO: Improve pane navigation.
Use this? https://github.com/christoomey/vim-tmux-navigator
It requires a VIM plugin as well, so I'm not sure.
