Add Drop Downs for Custom Objects (In App)

Idea Just came in my head where what could be super helpful especially when Users will be creating a lot more Custom Objects for Dynamic Content, is to have the ability to create drop down folders for Custom Objects, It would create a new element of Organization so not all objects are just across one line and then bunched together when not all objects fit on the Nav Bar. That wat instead of placing each Object on the Nav bar in a linear fashion, but we can go in and organize them based on Subject. Not sure how complex that feature would be but it could be super useful for Dynamic Content users.
