Menus Custom Modules


So we are finding that the Advanced Menus it not very sophisticated at this time and was wondering if anyone has developed or know of a custom built module that does what the Advanced Menus does? Because you cannot just clone or copy an advanced menu to another portal, so build a custom module would be the next step. All the documentation I found in here: all mentions creating modules but still using the Advanced Menu tree, so just curious if anyone has built a module that bypasses the Advanced Menus but still creates a navigation and tree list to display.
