Idea Summary
I would like to have a tool that shows a tree like structure that represents all the pages and the Navigation Menu entries of an application and all the links, branches and calls of the Menu and the pages that they do to each other, caller and called. Also show the pages that are no more in use, without any call, link or connection of any type. 

Use Case
The app that I am working with is full os lost code, pages etc that I do not feel secure to just erase the resources that I am not sure that are no more in use.

Preferred Solution (Optional)
Offer a new Workspace or Application Utility
