Add dropdown to breadcrumb on top of item list

I love the breadcrumb on top of the item list, it really gives a sense of “locus”.

The current right-click behaviour on part of the breadcrumb, is that DT proposes between opening it and revealing it.

I’d wish for it listing its siblings (other groups within parent), which would allow peaking and accessing the structure around the current locus without changing the window focus.

Thanks for the suggestion, noted for future releases.
