I was standing up a demo site for a potential client and figured I'd
simplify things a bit, so I decided to remove the "Lists" and "Libraries"
headings as I would do in 2007. Imagine my surprise when it told me that
doing so would remove the items underneath -- and sure enough, they were
gone!
I tried re-adding hard-coded links to the missing lists, and it prompted me
to select a heading under which to list them. So I can add a "heading" or a
"link", but I can't swap them in the hierarchy, and it would appear that I
will also lose some of the dynamic linking ability that we get with the
auto-generated links. Is that correct? It seems like a great step backward
for SharePoint.
