Is there today an easy way to achieve the following with biblatex and 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...
