The rationale behind the new navigation setup is that only significant articles should to be linked. We also pruned a lot of other "minor" articles from the list other than characters. It's entirely possible to link to a lot more articles – we actually have the ability to link to Level 5 submenus, which is one level deeper than the individual episode menus – but the idea is that the navbar should only be linking to major articles in order to avoid clutter and oversaturating things. Basically, it would be a lot harder to find what you're looking for if everything else were also lumped in.

That's the rationale, anyway. I'm actually with you on the matter of including more characters. If it were up to me I'd certainly have a lot more characters in the navigation bar. If you really do feel strongly about it I suggest asking Minomelo.
