working menu navigation

...but not working the way I'd like.

The menu navigation as described in http://www.coagula.org/content/pages/tutorial-manage-menu-and-lcd-display-arduino lays peers out horizontally, but Menubackend really expects them vertically.

I really liked the horizontal peers thing. I'd even hoped to be able to animate the menu movement left and right, but Menubackend doesn't send the direction of the menu movement with the menu change events.

Even with horizontal peers, however, I'm not sure it'd be quite what I imagined. It just doesn't feel right.

Anyway, redoing this using the more normal vertical menus.
