What's Wrong?

I sent a paragraph-long, carefully-crafted prompt to initiate a whole session of work, then switched away from that screen. Apparently I was in a cellular dead zone. I got the message saying the message didn't send and AFAICT everything I typed was thrown away _entirely._

What Should Happen?

Not waste my time? How about opening the session window before actually attempting to create the session, so my prompt is still there? Or leave it as the default for another session creation? Heck, a modal dialog saying “lol I suck but here's your prompt for C&P purposes” is a solid thought.

Steps to Reproduce

Go to New Session and give it a prompt when you don't have data. Observe that you can no longer observe your prompt.

Sonnet (default)

Is this a regression?

I don't know
