Navigation through directory without breadcrums

The breadcrums support is o.k. but it has some limitations. You get the whole path including the menu items, it is in the breadcrum position and if you add text above the file lists it is not clear you can use it to navigate the directory tree.

It would be much better to have the option to have some navigation directly above the file / directory list that show where in the structure you are and allows you to move back a level.
