Hi and thanks for replying!

This is a good point, but of much larger scope than just replacing the
follower of the basic citation-processor.

Notes and PDF depends heavily on user preferences - and should maybe be
left out for now? org-ref allows customizing org-ref-open-pdf-function,
with a default one using bibtex-completion-find-pdf, which finds a pdf in
bibtex-completion-library-path called citekey with one of the extension
listed in bibtex-completion-pdf-extension.

Maybe it is a good idea to start small, for example provide
1. Open bibtex-entry
2. Copy DOI
3. Opening DOI/ISBN/URL links in browser

Further functionality can easily be added per user, and good solutions
incorporated by default in the future?

I have played some more with this - would it be a good idea to include
macros to get citekey, datum and _? I would be happy to clean this up a
bit, add DOI/ISBN/URL-functionality, documentation and prepare a bug 
report/patch.

(defmacro org-cite-basic-follow--citekey ()
  '(org-element-property :key (car (oref (transient-prefix-object) scope))))

(defmacro org-cite-basic-follow--datum ()
  '(car  (oref (transient-prefix-object) scope)))

(defmacro org-cite-basic-follow--_ ()
  '(cadr (oref (transient-prefix-object) scope)))

(transient-define-prefix org-cite-basic-follow (datum _)
  "How should we follow references?"
  [["Open"
    ("b" "bibliography entry"
     (lambda ()
       (interactive)
       (org-cite-basic-goto
        (org-cite-basic-follow--datum)
        (org-cite-basic-follow--_))))]
   ["Copy"
    ("d" "DOI"
     (lambda ()
       (interactive)
       (kill-new
        (save-excursion
          (with-temp-buffer
            (mapc #'insert-file-contents org-cite-global-bibliography)
            (bibtex-set-dialect (parsebib-find-bibtex-dialect) t)
            (bibtex-search-entry (org-cite-basic-follow--citekey))
            (setq doi (bibtex-autokey-get-field "doi"))
            (replace-regexp-in-string "^http://dx.doi.org/"; "" doi))))))]]
  (interactive)
  (transient-setup 'org-cite-basic-follow nil nil :scope (list 
                                                         datum
                                                         _)))
