Theme Builder

Thank you, I think I get it, but I'm not too sure.

Is it that each tab is a space, and then the menu bar below it contains all of the menu bar options, hidden by team-label?

Guy will be able to advise in more detail, however as a general rule what we do is setup a block of wiki markup which does various builder-show/hide checks which then use the {set-flag} macro to setup a bunch of flags, for example:

{set-flag:user-unknown} user-unknown

{builder-hide:action=logout}
  {builder-show:group=confluence-users}
    {set-flag:user-registered} user-registered
    {set-flag:user-unknown|state=false}
    
    {builder-show2:group=adaptavist}
      {set-flag:user-adaptavist} user-adaptavist
    {builder-show2}
    
  {builder-show}
{builder-hide}

This content is added to (or more often imported into) the flaglogic.wiki resource attached to the layout .. this resource gets rendered before any of the panels and it's output is only enabled when debug mode is enabled - the intended usage is to allow you to setup a bunch of flags which mean something in your context and the use the flag= parameter which has been added to a number of builder macros to allow you to display/hide content.

As ever the confluence notation guide is your most accurate source of documentation for these macros.
