Sorry, I really did not mean to offend you.
It's too early in the morning for 100% accurate posts. ;-)
I just checked the help tab - which I completly commented out in my head until now... ;-)
Does not seem to be there at the moment. :-(
Manually editing for each page is not really an option. ;-)
What do you think about this feature? In my eyes it is a very important SEO component. Because, for example, a page title looks like this at the moment:
page title - site name
and could look like
page title - parent page title - grand parent page title - site name
I would say that a lot of sites work that way, which makes an impact on search engines but also how much users might click on the link shown in the search result. Also if the page is bookmarked it speaks for itself better.
