Font Styles (nice to have font style to fastly change all same style font through all pages)
It would be cool to use font styles like in the Microsoft products. You can add the document style once and after that change all document fonts through the all pages just changing the source style.
You can also choose the right style very fast and your prototype would be consistant
i.e you have to change all H1 title from 22px to 18px. You can change just style and all H1 become 18px through all pages
very usefull to have styles for other objects. For example, you can use just 3 type of buttons on the site. Master, widget and template don't works with it because, if you need to change button color for the all pages, you have to change all buttons!!!
