How can I make sure, that the document settings of a child document are compatible to the master document?
Today I had a big hassle concerning citation:
If I choose "citation style standard (numerical)" in the master document and "natbib" in the child document I get in the "insert citation window" (in the child document) the options that belong to natbib package (citet, citep, citeauthor etc.). Trying to render the document gives an error: "control sequence undefinded" (obviously, as the \citet is only defined in the natbib package, which I haven't included (in the master, at least)).
Do I have to keep master and child settings in sync manually? Shouldn't the be possible to be done automatically or are there use cases where different settings are useful? I expect a behaviour just like LaTeX, where it is also possible to have subdocuments without any header.
This problem: LyX BibTeX with child-documents not working was obviously caused by the same issue.
