I like the idea a lot.  It's a breadcrumb trail of the program
structure, generated dynamically.  You can sort of do this with
`selective-display' if your indentation is consistent.

The extra buffer interaction to get interesting info seems annoying.
How about using `header-line-format' to display the breadcrumb
automagically, in addition to the popup detail?
