tmux or screen are mandatory to use Wazaterm to keep the sessions because your browser sometimes stops the connection due to becoming standby or disconnecting wifi. But every time you type tmux attach is tiresome. To automatically start tmux after login, you can add the below lines into ~/.bashrc
if [[ -n "$PS1" ]] && [[ -z "$TMUX" ]] && [[ -n "$SSH_CONNECTION" ]]; then tmux attach-session -t work || tmux new-session -s work fi
