Yes, indeed

The general design only allows two options (and their values) to be passed to =biblatex= (in the =#+cite_export:= line): =bibstyle= and =citestyle=. However, =biblatex= can take many more options. Currently (correct me if I am wrong), the two alternatives to pass more options is to use a =org-cite-biblatex-options= or a line like this

#+begin_src org
  ,#+LaTeX_HEADER: \usepackage[bibstyle=numeric-comp,sorting=none, hyperref=true,backref=true,url=true,backend=biber,natbib=true]{biblatex}
#+end_src

Precisely.

One of the attachments showed what I considered to be all possible cases: the new string (containing =style==; it could be either =bibstyle==, =citestyle==. It is similar to the case which allows for ="bibstyle/citestyle"=, as documented on line 34 of =oc-biblatex.el=). Currently (these could, hopefully, also be used for the documentation), if somebody uses

1. case
   #+begin_src org
     #+cite_export: biblatex "how/much"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=how,citestyle=much]{biblatex}
   #+end_src

2. case
   #+begin_src org
     #+cite_export: biblatex "how" "much"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[style=how]{biblatex}
   #+end_src

3. case
   #+begin_src org
     #+cite_export: biblatex "how,opt=true"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[style=how,opt=true]{biblatex}
   #+end_src

4. case
   #+begin_src org
     #+cite_export: biblatex "how/much,hack=true"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=how,citestyle=much,hack=true]{biblatex}
   #+end_src

5. case
   #+begin_src org
     #+cite_export: biblatex "citestyle=corner/much"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=citestyle=corner,citestyle=much]{biblatex}
   #+end_src

6. case
   #+begin_src org
     #+cite_export: biblatex "citestyle=corner/much,opt=true"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=citestyle=corner,citestyle=much,opt=true]{biblatex}
   #+end_src

7. case
   #+begin_src org
     #+cite_export: biblatex "bibstyle=corner"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[style=bibstyle=corner]{biblatex}
   #+end_src

8. case
   #+begin_src org
     #+cite_export: biblatex "bibstyle=corner/much"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=bibstyle=corner,citestyle=much]{biblatex}
   #+end_src

9. case
   #+begin_src org
     #+cite_export: biblatex "[bibstyle=corner/much]"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=[bibstyle=corner,citestyle=much]]{biblatex}
   #+end_src

10. case (note that this can be combined with all the above)
    #+begin_src emacs-lisp
      (setq org-cite-biblatex-options "nulloption=true")
    #+end_src

    #+begin_src org
      #+cite_export: biblatex "how/much"
    #+end_src

    the result is
    #+begin_src latex
      \usepackage[nulloption=true,bibstyle=how,citestyle=much]{biblatex}
    #+end_src

whether some of these are broken is up for discussion. The suggested patch adds one conditional case, which searches for ="syle="=, takes away the brackets and turns the above cases into:

1. case
   #+begin_src org
     #+cite_export: biblatex "how/much"
   #+end_src

   same result as above

2. case
   #+begin_src org
     #+cite_export: biblatex "how" "much"
   #+end_src

   same result as above

3. case
   #+begin_src org
     #+cite_export: biblatex "how,opt=true"
   #+end_src

   same result as above

4. case
   #+begin_src org
     #+cite_export: biblatex "how/much,hack=true"
   #+end_src

   same result as above

5. case
   #+begin_src org
     #+cite_export: biblatex "citestyle=corner/much"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[citestyle=corner,citestyle=much]{biblatex}
   #+end_src

6. case
   #+begin_src org
     #+cite_export: biblatex "citestyle=corner/much,opt=true"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[citestyle=corner,citestyle=much,opt=true]{biblatex}
   #+end_src

7. case
   #+begin_src org
     #+cite_export: biblatex "bibstyle=corner"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=corner]{biblatex}
   #+end_src

8. case
   #+begin_src org
     #+cite_export: biblatex "bibstyle=corner/much"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=corner,citestyle=much]{biblatex}
   #+end_src

9. case
   #+begin_src org
     #+cite_export: biblatex "[bibstyle=corner/much]"
   #+end_src

   the result is
   #+begin_src latex
     \usepackage[bibstyle=corner,citestyle=much]{biblatex}
   #+end_src

10. case (note that this can be combined with all the above)
    #+begin_src emacs-lisp
      (setq org-cite-biblatex-options "nulloption=true")
    #+end_src

    #+begin_src org
      #+cite_export: biblatex "how/much"
    #+end_src

    same result as above

In this way, =org-cite-biblatex-options= is completely optional (an addendum to =#+cite_export: biblatex=), and more options (other than =bibstyle= and =citestyle=) can be added next to =#+cite_export: biblatex= (without hacks in between lines, as shown above).

Anyway! the "for your consideration" already implies something, and I can live with an extra =#+latex_header:=.

Sure. I hope that the code above suffices :) . I compress, because I don't have unlimited space in my account.
