I'm used to clickable breadcrumbs in the Addressbar (Explorer and other File Managers implement a version of this).
Implementing such, would likely be an undertaking. Thus I thought perhaps it could be displayed somehow on the TAB via a modifier click (Shift+Click or such)... only to realize right clicking on the Tab icon already does show a vertical breadcrumb list...
Perhaps mention a little blurb about this in the BreadCrumb and Tab documentation in the help file.
