Menu's UI and URL hierarchy, need help…

Heya,

As much as I like the UI for Menus, every one of my clients (150+ WordPress sites) complains that the Menu interface is confusing. Their complaint is rooted in the fact that the Menu’s UI has no affect on the URL structure. Thus, requiring them to navigate back to Pages and manually set the order.

Historically, I’ve used “Simple Page Ordering” plugin and only use the Menu’s UI for secondary menus, but it seems to me that there should be a simple checkbox that says something like “Reflect hierarchy in URL’s”.

Does anyone know if this, or something like it, exists? Or can anyone suggest a better practice? Thank you!
