When the first page of a Wiki is displayed, the breadcrumb shows “Wiki”. After navigating to other pages inside the Wiki, the “Wiki” breadcrumb is gone and only the page title is shown.

Some users were confused and could not find the page again when they jumped to other pages as they did not know it was a Wiki page.

I suggest to always add a “Wiki” breadcrumb by default whenever a Wiki page is shown - or at least an option to enable this.

Another solution might be to automatically create a new Wiki page as a sub page of the currently visible page. Thus all pages will at least become a child of the main “Wiki” page and the breadcrumb would be there.
