(WIP) feat: support \thanks in title page

[jolars]

Closes #44.

[jolars]

It's trivial to just enable this feature again, but it doesn't look great by default and I am having a hard time customzing the appearance of the content of \@thanks. It seems to ignore \usebeamercolor etc. Maybe someone who's more of a latex wizard (nudge nudge, @samcarter) could help figure this out? I am not even 100% sure where it is defined. I see that beamer is employing various hacks around this, like here: https://github.com/josephwright/beamer/blob/fef8f1b049516cebfc2eda4ca34e64cf17e544ec/base/beamerbasetitle.sty#L55-L62.

\insertthanks is also I guess empty? Not sure why.

[jolars]

Maybe you have some thoughts, @rezahousseini?

I am not even 100% sure where it is defined.

It is defined in the format, see texdoc source2e for the definition.

It seems to ignore \usebeamercolor etc.

Beamer does not make any special changes to \thanks. As it is basically just a footnote, you can adjust it's colour etc. the via normal footnote templates/colours/etc.

For example:

\setbeamercolor{footnote}{fg=green}
\setbeamercolor{footnote mark}{fg=red}

Great, thanks a lot! I think I know how to deal with this then.

cool very responsiv! looks good, as far as I know it's a footnote as samcarter mentioned

[samcarter]

\insertthanks isn't defined, no need to test. Maybe just keep the beamer definition of the title page? \def\titlepage{\usebeamertemplate*{title page}\@thanks}

Thanks for raising the issue. It seems like it was actually purposely disabled in metropolis, but I don't see why we shouldn't support this. I will wrap this up at the latest next week. It is a little more tricky that I thought since I need to make a temporary modification of the footnote-related commands, add a new beamer template for dealing with the thanks command, and figure out the spacing on the title page.

Thanks, yes, that's a good idea. I'll change it.
