In the Rich Forms product it would be nice to be able to preview the form that you are developing instead of having to save the form and then open an item to test the form.
The Test button is there and I have used it before to test the functionality of an expression or item that I am creating on the form.
What I am asking about is the ability to preview a form before it is published. This way you can see how the form looks, how fields are positioned and possibly how the form works. This way you are not thinking that the form works well or is laid out well and then you get negative feedback from the end users.
