I’m sorry if this question is redundant. I’ve browsed existing resources but didn’t find a clear answear.
My goal is to build an open registration multisite network for my users. I want to let them choose from a selection of themes, but to keep the site “browsable” I want to use a global header to link between blogs and the homepage. But I also want to use this space for functions useful to logged in users, replacing the admin header bar. For tests I have used your excellent Ultimate branding plug-in but this only lets me insert static html of course. The question is – what is the best way to create a global network wide header that would consist of some static elements and a few dynamic ones – specifically – login/logout/register buttons, search field, wp-admin link for logged in user etc…
