Please allow me a further question regarding *.kepub.epubs
I realize now, that the reading options of kobo glo like e.g. the line height are not overwritten by a corresponding global user style, like e.g.
Code:
p { line-height: 1.4 !important; }
in \.kobo\kepup\kepub-book.css
It seems, that the reading options have a higher rank than even the global "!important" rule.
Is there any way to give the rules in kepub-book.css a higher rank?
In other words: I like to loose

the option to declare reading options for individual books.
Is it true, that using the universal css selector "*" in kepub-book.css causes problems in the Kobo.
I recognized an extremly long loading time. But I'm not sure, if really that is the cause.
