I notice WA plan to add more new design theme for website template. Is it possible to add some theme with options to add pages/nevigates on horizontal level, I mean right below the header?

Also can we add a page, when visitors click that page on navication bar, it will be directed to an external site - since WA doesn't have templates for blog and forum like wordpress does, I am thinking to have a Wordpress blog of my own and just use a link on WA nevigation bar to redicrect visitors.

Can It be realized in new themes?
