Ok, I'm trying to find some good prototyping tools that can be used for designing WP8 apps. Something that will build out at least a semi-functional prototype to help me envision it so I can send better specs to my developer. Now, I'm more on the information architect/design side of things and definitely not a coder, though I can do some very minor development. Can you guys recommend anything that would allow me to at least hash out the look and feel of an app and possibly fake the functionality? Thanks in advance.
