Howdy this is my solution:
\documentclass{beamer}
\usepackage{etextools}
\makeatletter
%Here comes the Framelist
%
\newcommand{\printframelist}{ }
\newcommand{\@savefrml}{ }
\newcommand{\frameliston}{%
\let\oldframetitle\frametitle
\newcommand{\tgframelistfronthook}{$\cdot$}
\newcommand{\tgframelistbackhook}{\\ }
\newcommand\myaddto[1]{%
\write\@auxout{\noexpand\@writefile{frml}{\noexpand ##1}}}
\renewcommand{\printframelist}{\@starttoc{frml}}
\renewcommand{\frametitle}[1]{\oldframetitle{##1}%
\xifstrequal{##1}{\@savefrml}{}{
\myaddto{ \noexpand%
\tgframelistfronthook ##1 \noexpand\tgframelistbackhook}%
}
\global\def\@savefrml{##1}%
}
}
\makeatother
\frameliston
\begin{document}
\frame{\frametitle{FIRST}}
\frame{\frametitle{Second}}
\frame{\frametitle{Third}}
\begin{frame}
\printframelist
\end{frame}
% The following should turn the framlist off for one slide when\anotherft is used
\let\anotherft\oldframetitle
\frame{\anotherft{FIRST A}}
\frame{\frametitle{Second A}}
\frame{\frametitle{Third A}}
\end{document}
This uses the very basic LaTeX mechanism on creating external files (like toc). extetools are used to compare strings and decide to print or not to print the title (for overlays). See in bitbucket.org/tobig/hohenheimbeamertheme/
Redefine \tgframelistbackhook
and \tgframelistfronthook
as you please.
EDIT: What you are showing in your example given above is that you put the whole columns
stuff into the frametitle. And it breaks. Remember the frame
environment is defined as
\begin{frame}<⟨overlay specification⟩>[<⟨default overlay specification⟩>][⟨options⟩]{⟨title⟩}{⟨subtitle⟩}
⟨environment contents⟩
\end{frame}
(see beamer documentation)
The first brakets after \begin{frame}
will be interpreted as the title.
This will work:
\begin{frame}
\Huge
\vspace {0.35\textwidth}
% Don't remove
\begin{columns}
\begin{column}{0.3\textwidth}
\end{column}
% Don't remove
\begin{column}{0.3\textwidth}
\textbf{Thanks!}
\end{column}
% Don't remove
\begin{column}{0.3\textwidth}
\end{column}
\end{columns}
\end{frame}
.log
file? Are you interested in a macro like\showmyoverview
that should print the slides?
