Beginning to capture some ideas from improving the menu:

• Code for the menus should be segregated between the technical implementation and the layout - making it easy for non-technical users to customize the menu.
• Define the customization of the menu in CSV?
• Make Menu customization completely independent from the modules.
• How many levels? Configurable.
• Breadcrumbs
• Allow modules to be turned on/off and also excluded from releases of code with simple switches.

Allow the user to define a custom home page, without editing core code.
