Breadcrumb mode is a useful companion to imenu. The usability could be
increased if mouse click actions in the tabline would provide better
defaults:


   1. When clicking on the deepest displayed node (leaf), provide a search
   where to jump to (as it is now)
   2. When clicking on a non-leaf and this item is not a type bucket
   (method, typedef) but a concrete item, jump to that item, otherwise provide
   the search as in item 1


Especially point 2 would be helpful when navigating hierarchical structures
like the outline of a markdown or org file.

Best, Johann

Hello Johann,

Patches welcome for this, the current mouse click actions are
just fairly dumb placeholders for something better.  Your idea sounds
good, though I don't understand what you mean by "provide a search".
You can figure that out later.

Anyway I don't use the mouse much myself and don't have many resources
to implement this.  If you don't know much Elisp, this could be a good
opportunity to learn.  Else try to lobby someone on emacs-devel or some
other forum to help you with your idea.

João
