Secondly I've tried to find options on how to make it move everything into
just 1 HTML-file. It seems that under the standard setup footnotes are put
in separate files.
I hate that too. For the TeX Live documentation, either Eitan or CVR
advised me to do the following, which works for me:
% have html in one piece (including footnotes).
\Preamble{charset=iso-8859-1,html,info,fn-in}
...
\EndPreamble
It's the html,fn-in which is relevant to the problem at hand; the other
attributes are unrelated.
I have this in a file named live4ht.cfg. Then in the document I end up
calling:
\RequirePackage[live4ht]{tex4ht}
Hope this helps.
