Specifying a package in Module declaration

[ehud.behar at protonmail.com]

Thanks a lot for your reply.

1. The geometry package is not listed in Appendix A of the customization manual, and I tried passing it to Requires but lyx doesn't add \usepackage{geometry} to the preamble. It does so when I specify a package that is indeed listed in the appendix.

2. I didn't understand. When using the additional argument inside the [] in the module specification, should LyX add the \uspackage{} line to the preamble or not?
