Re: #ShakespeareDIY, I would love this feature. When I use it, it's doing about $0.24 per task it performs, or ~$3 per prompt...In a perfect situation.

Simple, short prompts are around $4. If you're a no-code novice and just there to play, which is how I started with it, you won't spend much. My first apps were pretty cheap, the most expensive one cost $27.

If you're diving deeper, continuing to prompt it, you will rack up the $$$$

You can try messing around with prompt ideas in the free Gemini Flash Playground first to refine the idea (and see what it's able to do). I do that sometimes too. Only because I find often that the first iteration of something comes out and THEN I realize what I should have asked it to do.
