* Non-technical feedback ::
 - Thank you so much for sharing. I've been looking for something like this for a while.
 - I hope it'll make it into org-mode some way or another, it seems like a valuable addition. 
 - imho the HELM integration is essential.

Subject: [O] Function that jumps to an entry with a certain CUSTOM_ID

Hi all,

the following function has served me well for a few years, so I thought 
I'd share it.  I would even be happy to contribute it to the codebase of 
org-mode (core or contrib); however in this case someone would have to 
point me to a fool-proof guide for how to do this.  I know that for 
contributing code I will have to sign some FSF copyright forms, and I 
know how to use git, but I don't know the exact org-mode specific steps 
of doing so.

--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---
(defun org-jump-to-id ()
   "Asks for an identifier and searches for the first entry in the 
current file that has this identifier as a CUSTOM_ID property."
   (let* ((property "CUSTOM_ID")
          (custom-id (org-icompleting-read "CUSTOM_ID of entry: "
                                           (mapcar 'list 
(org-property-values property)))))
       (org-link-search (concat "#" custom-id))))

(define-key org-mode-map (kbd "\C-cj") 'org-jump-to-id)
--- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< --- %< ---

This implementation works efficiently in a 4 MB org file with 100 IDs. 
Together with ido or helm I find it a very user-friendly way of jumping 
to frequently used headlines.

I noticed that org-babel-ref-goto-headline-id does something similar, so 
maybe some code could be shared among the two functions.
