I've changed to using Texpad as my LaTeX editor and am very pleased with it, and use XeLaTeX and Biber for my documents.
However, now when I try and compile a Scrivener document using MMD -> LaTeX and open the resulting .tex document in Texpad, it defaults to the built-in Texpad typesetter and bibliography engines, and the document fails to compile.
Is there any way to set XeLaTex and Biber as the typesetting/bibliography engines via Metadata/LaTeX options in Scrivener? I can find very little help with regard to LaTeX setup in the Scrivener tutorials, and am usually on the verge of abandoning Scrivener and going back to LaTeX alone as everything always seems so difficult to get working, and breaks every time there's a Scrivener upgrade

Thanks,
Emma
