Change header modules
You can use a different header module at any time. Each header module offers a different layout and set of options.
If you use a Compact header from Journal > Header > Compact and which to use a Classic header module from Journal > Header > Classic, you would create a new Classic module, then assign it to the skin in Journal > Skins > Edit > Header > Desktop Header, then edit the module to your needs, add menu modules, styles, etc.
You can quick-edit the header module directly from the skin (small pencil button seen when hovering over the module option) or go back to the module in Journal > Header > Active Header (Classic in this case) > and edit it there.
