I really like the inclusion of a prompt and I was just thinking that the ability to place select options from a drop down menu for the prompt (or use text as default) would cool (like selecting from multiple players attributes for example). The ability to place a macro/attribute within the prompt would be cool too. These 2 suggestions can be worked around by placing the exact formula/value in the prompt with a little extra work. my suggestions are more for making these certain situations work faster.
