Since we have "Master pages" for groups of similar pages, why don't we use the breadcrumbs navigation?
If you don't know what is that thing, look at the line below this thread's title, the one that says "Forum » Suggestions/Questions / Suggestions". It is automatically used on the Forum, but it would be great to also use it on pages.
I mean, just look at this "Nexus > Neon World > Red and Blue World > Hospital > Bone Maze > Red Monster > Flesh Walls > Deranged Mouth World" right in the text of an article! It doesn't look very convenient.
