I immediately fell in love with the "Top Navigation" part and began implementing it right away in all my existing files. But its many merits come at a price: As soon as I install a "Top Navigation" part on a layout, I'm no longer able to see "Page Margins", even tho I've got them turned on, and they show up again if I delete the "Top Navigation" part.
Like a kid faced with a choice between chocolate cake or vanilla ice cream, I want them both. Can't I have them both, please? Pretty please!? They go better together.
