I haven't used pp+.el before.  So consider two independent
upvotes... for this request.

To add to your list:

1. Undo in pp eval outputs.  (There is a separate bug for that)

2. Linkify circular references.  So that when I click on a circular
   "reference" it takes me to the "site of definition".

----------------------------------------------------------------

The above two requests are not hypothetical requests.  

The new `org-element.el' library lispifies an Org buffer and it uses
`:parent' pointers to boot.  So, for complex outlines and for operations
that non-trivially manipulate the lisp tree, examining, manipulating and
persisting a lisp tree is a REAL need.
