In any new version of NOF I would like to see better themes and styles and the old ones removed.
Being presented with "Cityscape - Teal" is like going back to the 90's!
I love NOF for the speed at which a sites structure can be completed and the auto creation of buttons and banners. Providing loads of great new ones would make it brilliant. More "Web 2.0" styles (much as I hate that phrase).
