Nested Quick Menus....

The quick menus are great, but you're unfortunately are limited to only 6 shortcuts. I would love to see an option for nested quick menus, so that when you select one of those six, you have the option to open another quick menu. This way you can go from 6 to 36 shortcuts. 

Of course, it would have to be optional. You should still be able to to use the original quick menu as you do today, for things you need quick access to (e.g. Undo), but then have an option to have a couple of them expand to new quick menus for features you use less often.
