Brainstorming feature doesn't save your work but pushes for long ideation

The standalone Brainstorm tool encourages long ideation sessions with repeated 'Generate More' prompts, but it doesn't clearly indicate that the results are ephemeral (temporary). A history panel or automatic session saving would prevent users from losing hours of creative work. I spent 4 hours obtaining excellent historical data, conversations, etc not knowing that each time I pressed another idea my information was lost forever.
