Please add prompt count to settings

[Sana-A-E]

I find the ability to have several prompts set and then switch between them extremely helpful in my workflow. In fact, I find them so helpful that I'd like more of them. It would be nice if we could set the number of prompt slots in the settings so everyone could add however many they need.

Or from a usability perspective, it would actually be even better if there was a plus button next to the prompts allowing one to add one more if and when they need it. But, of course, just a prompt count setting would do too.
