Actually, for the structure and the breadcrumbs you only need to edit
the wikitrail page.
You are not required to edit the Berlin page, or any other page, unless
you want to link from that page to the new page.

Oh, WikiGroups are simpler than that, and you are familiar with them.
"Main", "Site", "SiteAdmin", "PmWiki" are WikiGroups in the default
installation. So both Main.Maps and Main.Guides are "pages" in the group

This looks cool.
Instead of "global $pagename;" I recommend to use
which will import the current $pagename passed by MarkupToHTML which may
not be the same as the global $pagename.

If the wiki has UTF-8 enabled, I'll probably use an arrow like → or a
middle dot · or a right quote » or some other Unicode character.
Because it is unlikely that your users' keyboards can easily type this
Unicode character, I'd add a GuiEdit button with the character.
