Hi,
since the structures have a "name" beside the "title" it's very
difficult to create internal Links when you renamed (rather "retitled")
a structure.
You have to always remember the name you gave the structure first
because if you want to create internal links you have to use now this
name else the link is broken. I don't think thats a good Idea because no
one can guess the hidden "name" of structures....
