I like the idea of LyX, and its GUI, the implementation is showing its age a bit. Starting from scratch today it would be better to implement in Rust using XML as the .lyx document format and XSLT and XSLs for transformations to LaTeX and other output document formats. EDIT: And there are XSLs for such conversions. E.g., http://getfo.org/texml/ http://getfo.org/texml/
