Hi fellow themers --
It seems like the "Navigation" block is kinda forced into Drupal's otherwise amazingly themeable system. I'm interested in designing some themes which do NOT use a hierarchical collapsable menu-tree for navigation and especially administration. Right now, it seems I can't theme-away the tree-style menu.
Does any module exist or is there any plan to untie Drupal from the hierarchical navigation system? I realize there's no direct way to create the same functionality as the tree-style design, but I'm thinking maybe abstracting the admin menu (and others too, but the admin menu is what really stops me from designing themes without a tree-style menu) into multiple pages, which should hopefully bring back the functionality of nested menus.
I'm thinking that if something like this does NOT exist, maybe it's worth adding a module or contributing to the Drupal core so one could automagically generate non-tree style menus by having Drupal generate multiple subpages that correspond exactly to each subtree in the tree-style menu.
Hopefully someone knows if this functionality already exists, otherwise I have intentions to implement it! 8-)
Do I sound crazy, or does this make sense? It's motivated by the fact there are a lot of wonderful web designs that are incompatible with the hierarchical tree-style menu necessary to administrate (is that a verb?) Drupal.
