thanks for the interesting contribution! Have a look at the patch
I hopefully don’t forget to append.
I didn't quite understood how this works:
\unexpanded\def\startframe{\dosingleempty\frame_start}
This creates the new command \startframe which calls the internal command
\frame_start which has one optional argument.
\def\frame_start[#1]{%
\iffirstargument
\section{#1}%% solution needed here!
\fi
This block checks if the optional argument is used by the user, when the
argument is used the content is typeset as \section.
\begingroup
\grabbufferdata[simplesteps][startframe][stopframe]%
}
With the \grabbufferdata command the content beginning from \startframe until
\stopframe is stored in a buffer with the name “simplesteps”.
\let\stopframe\simplestepsplaybuffer
This makes the \stopframe command a synonym for \simplestepsplaybuffer which is
now called when the frame environment ends.
best use a namespace: \simplesteps_start_frame
(dangerous name: \startframe ... could be core name)
