with plugins like market press, and grid market theme, alot of us are thinking of etsy style sites. one major limtation i find is the navigation. because all the sites would have there own header this would create confusion. if there was a way to have one global header, then the sidebar would represent the stores categories etc, while the header and header menu would represent the network wide stores, and global products.
is there a way to make one header, with menus, logos, and get it to display sitewide?
