Org-cite: Replace basic follow-processor with transient menu?

["Tor-björn Claesson" <tclaesson@gmail.com>]

Hello!

I recently switched from org-ref to org-cite, and would like to thank
eveyone who has worked on citation handling in org-mode!
Your work is of incredible value to my research productivity!

Since I use org-roam-ref, I initially went with citar and installed
vertico, marginalia and embark, but this felt a bit invasive,
so I went back to the built in basic processors,
which fill all my needs except for the follow-processor.

To improve following, I made a transient which offers options other than
opening the bibliography entry. This works really well, and can easily
be extended by adding new suffixes.

In order to make the basic follow processor more useful, would you be
interested in replacing it with a transient menu?

As an example, I attach my transient, including examples on extensions.
It would obviously need some work on wording and thought as to what
commands should be made available by default. Also I am not used to
elisp, and the code can probably be improved!

I hope that this example demonstrates how more useful and extensible
the basic citation follower would be in form of a transient menu,
and would be happy to work this into something fit for inclusion
in org-mode, in case you would be interested.

Best regards,
Tor-björn Claesson
