Is there today an easy way to achieve the following with
biber discussed here?
Unfortunately the code does not work for me as pdflatex produces an error after successfully doing a pdflatex+biber+pdflatex run of the code stated (without showing the footnotes) telling
! Undefined control sequence. <argument> \cbx@sortlist
It would be so helpful to have a command like \sfcite showing a sorted list of cites occuring on one page in the footnote area of that page and a complete reference list at the end of the document...
