I would like to see the ability to have Sub Collections for use with the Mega Menu, meaning that when you create a collection of T-shirts you don't have to create a T-shirts collection to work across many areas. Like in my store I have collections for "Outdoors" "Bearded" "Humor" "etc." and there are T-shirts for every one of these so I don't want to have to create a sub collection for each though but there should be way that the Mega Menu can read from both of these collections and see oh yes "All Bearded" or "Bearded + T-Shirt" and so on.
