A little off topic - but as long as we are talking about changing the menu system a bit... About a kazillion years ago I had wondered if we could allow modules to build 'custom' menus that were outside of the 'navigation' menu tree. I had proposed adding a few lines of code to menu .inc http://drupal.org/files/issues/menu_inc_3.patch (a bit out of date - but you get the idea). I was wondering if anyone has any new thoughts on the idea of modules not being so tied to navigation menu. Basically allowing them to build their own menus that are true menu system menus - (not just navigation jammed into a hook_block). At the time of the patch - I had a specific implementation in mind - where the book module would build a true menu system menu instead of the way it builds its navigation block. This concept would still apply regardless of the menu array structure. Any thoughts? Any other killer applications for modules building menus outside of 'navigation'? andre
