Problem or Desire

Since the name configuration can "also contain custom HTML for easier customization" (due to its primary/first use in the sidebar) using the name for page title generation can produce some ugly results.
(In relation to #2478)

Proposal

A. Allow for the definition of a title generator (pageTitleFormatter) as recommended by @Koooooo-7 in #2478
B. Keep the new use of name for title generation, but create a new configuration (sidebar) that could be used to modify the sidebar directly.
