A small but practical feature (at least for some types of sites) is that you can now activate Slide that generates Previous / Next buttons for navigating between pages on the same hierarchical level (read: with the same page parent). The list of pages is treated as an endless loop, so when you reach either end of the list it will start from the other end.
Note that Slide, Back and Home are completely independent (in this case all are activated) and they are in the above order and always at the end of any menu, and typically at the end of the page unless Position: Top has been set.
Navigation buttons adher to the Per row settings, and are in practice integrated with the menu. In this case there are no sub pages, so no menu either.
