Thank you for your quick reply,
please excute my late one ;)
Thank you, that did indeed help with the issue of configuration.
Skins do not seem to work that way though, since there are
unevaluated expressions smeared all over the page when I use a linked skin.
We updated to version 8.4.2 for this, due to EOL of the 7.4 branch in
January. Should there be any idea how to use linked skins, I would be
very happy, if not I'll just use the second approach (which is using
a separate volume for the skins)
