Option for a more serious look. Part of the charm of this product is it's hand drawn pencil look. However, when doing mockups for customers, it feels a little "cartoonish". My concern is that customers will think we're not taking them seriously. I want to use this tool but with the informal look I feel that I can't. It's a great tool for working with customers on what a software user interface will look like and coming to agreement on features and limitations quickly. However, I can't really use it unless it looks more serious.
