Feature Request: Continue previous session when reconnecting

It is my impression that when - as it happens occasionally - the browser locks up or one closes the localhost:8080 tab and reconnects the entire previous session is lost. I assume this is due to all vital data being stored in st.session_state. It would be desirable if there was a way to reconnect to the previous session and continue with the ongoing thread. Maybe there is a way in loop.py to continuously store the session information in a local file and on request restore that data?
