A column of sessions down the left of the interface.
The page held one conversation. It holds as many as you like now: click to switch, and a session is named by whatever you first asked it. They are written to disk, so they are still there after you stop the process - both the transcript you read and the one the model holds, because giving back only the first would be a conversation you can read and cannot continue.
Each conversation drives its OWN browsers. A chat and a session are one thing with one id, so the chat named lavoro reaches the browsers of session lavoro and no others, and deleting it closes them. A page that names no session and a client that names none both land on default and share a browser, exactly as before.
Saved conversations live under AIHAWK_HOME alongside the saved sessions.
