An article name currently appears exactly the same in the left-side navigation as at the top of the article page itself. This is despite the left-side navigation space being much more limited. It would be great to be able to specify a shortened article name for use in the left-side navigation, whilst maintaining the full article name in the article and search.

For example, if I'm documenting an "Acme integration", I might want one article to have two names:

Full article name: Setting up the Acme integration in your domain

Left-side nav name: Acme
