Add Subsectionpages to Beamer
It would be nice to have the subsectionpages of beamer also in the BFH CI:
\defbeamertemplate*{subsection~page}{BFH}{
\bool_set_false:N \l__ptxcd_content_separator_ruled_bool
\__ptxcd_content_separator:n {subsection}
}
\defbeamertemplate{subsection~page}{BFH-ruled}{
\bool_set_true:N \l__ptxcd_content_separator_ruled_bool
\__ptxcd_content_separator:n {subsection}
}
...
\def\subsectionpage{
\ifbeamer@inframe\usebeamertemplate*{subsection~page}\else\frame{\usebeamertemplate*{subsection~page}}\fi
}
