– CHRIS MAVRICOS
I’ve been working on a site which has too many menus and sub-menus however when you try to move or add a page on the menu editor, it hangs! It was driving me nuts so I tried searching and searching until I stumbled upon a site which I thought might help out in speeding up the menu appearance and functionality. He said that he has a PLUGIN than can fix the problem. 🙂
Here’s the link to the plugin: Faster Appearance Menus
