A nice and simple addition would be the allow the user to press escape when doing pick points to cancel out of it. There is no way to stop pick points once it's started. If I have a formula in the prompt and accidentally double click it, I'm screwed. I have been in the situation a few times where I edited a bunch of prompts for my product, then accidentally double click a prompt that has a formula I did not want to override and I'm forced to pick points for that prompt. Then I have to either find the formula from a related product or cancel all my other customizations. Simply pressing escape would allow me to not have to do that.
