UI Feature Request: save form data to local storage until submitted

I’ve found myself carefully constructing questions in the ChatGPT input box – it’s a great excuse to think through a problem, that’s not yet fully formed, that I’m exploring. My finger slipped and I closed the window, and my minutes of typing and thinking in preparation are gone.

It would be nice to have data typed into the input box, saved, in browser local storage, until it is submitted, so that accidental page closes don’t erase progress on carefully articulating a problem, a chosen phrasing.
